    1 INTRODUCTION
    ══════════════
    Welcome to Yilmaz DisAssembler Version 1.1 (TM). Yilmaz DisAssembler
    is an interactive and flexible disassembler which lets the user be a
    part of the disassembling process.

    This software disassembles executable files of format COM. That is
    not the only one, it can other file formats of one segment size, for
    example, Borland's TPU files. The disassembled file is fully
    compatible with Turbo Assembler and MASM. It needs additional work
    to be assembled again with above mentioned assemblers.

    This version of Yilmaz DisAssembler has following limitations:

         ■ Maximum executable file size is 64 KB.
         ■ Only 8086/8088 CPU instructions can be disassembled.
         ■ 8087 Math Co-processor's instructions.

    This software uses multiple windows to view the disassembled file.
    This will help the user to see different parts of the file
    simultaneously. Once an executable file loaded and disassembled, the
    user may open as many windows as he/she wishes to view the
    disassembled file. The only one restriction may be for him/her to do
    so is the available memory, which can be seen on the About dialog box.

    Yilmaz DisAssembler allows you to interact via dialog boxes to

         ■ load an executable file,
         ■ save the disassembled file,
         ■ change the default directory,
         ■ print the disassembled file,
         ■ convert a range of memory area between data and code areas,
         ■ go to a specified address inside the disassembled file,
         ■ insert and delete label at specified address inside the
           disassembled file,
         ■ customize the environment's colors,
         ■ choose the preferences,
         ■ and respond to occurred errors.

    This is a shareware program, i.e. you get a copy and try it. If you
    like it, and you think it worth its price then you pay the asked sum
    and you become a registered user.

    If you want the shareware principle works, and you want to see more
    good quality shareware programs at low prices, you should register
    this program. Send the author his fee. Read the license for more
    information.

    NOTE
    All suggestions about this software are welcome.

    2 REQUIREMENTS & FEED BACK
    ══════════════════════════
    Yilmaz DisAssembler requires

         ■ a compatible computer,
         ■ a graphics card, does not matter which one,
         ■ and at least 400 KB free memory at the start.

    A mouse device is optional but not required, that is to say: if you
    have one then you can use it.

    This software is tested and verified to disassemble correctly. It is
    free from known bugs as far as I know. Technical support is available
    at no charge for all users.

    You can contact me either by electronic post at FidoNet:

         Yilmaz Towfeek@1:201/111

    or by mail post at following address:

         Yilmaz Towfeek
         Box 10015
         580 10 Linkoping
         Sweden

    When reporting problems with this software, please include as
    detailed description of the problem as possible.

    3 HOW TO START
    ══════════════
    The correct syntax to start the Yilmaz DisAssembler is:

      YD[.EXE] [[d:] [[Path] FileName [.Ext]]]

    Where the parameters between big parenthesis `[]' are optional. If
    you skip the parameter at command line, then you just enter to the
    program integrated environment. If you type in the parameter, the
    executable file will be loaded and disassembled. The executable file
    (file to be disassembled) can be any where in your system, provided
    that its directory is DOS "PATH".

    To start this software, you do not need to be in the directory where
    "YD.EXE" and all required accompanying files are. Be sure this
    directory is in DOS "PATH".

    NOTE
    If the configuration file "YD.CFG" does not exist either on a path
    directory or default directory, the program will end immediately
    without any message.

    4 INTEGRATED ENVIRONMENT
    ════════════════════════
    The integrated environment consists of the following 3 parts:

         ■ The menu bar at the top of the screen.
         ■ The Desktop.
         ■ The status line, a quick reference line at the bottom of
           the screen.

    The menu bar for Yilmaz DisAssembler Version 1.1 contains these five
    main options: File, Edit, Option, Window and Help. These options may
    be accessed in three ways. First, press the F10 key to show the menu
    bar and then use the <LEFT> and <RIGHT> arrow keys to highlight the
    desired option. Select the right option by highlighting. Press the
    <RETURN/ENTER> or <DOWN> arrow key to execute. You can also press the
    first (highlighted) letter of the desired option name.

    A second way of accessing a menu bar item is by pressing the <ALT>
    key and the first (highlighted) letter of the desired menu item's
    title (name). For example, to pull down the "File" menu item you need
    to press <Alt> and "F" key simultaneously.

    The third way of accessing a menu bar item is by clicking with the
    mouse (if you have one) device on the desired menu item.

    Once a menu bar item is executed, a pull-down menu will be displayed
    with the last selected menu command highlighted. You may execute a
    menu command by using <UP> and <DOWN> arrow keys to highlight the
    right command. Then press the <RETURN/ENTER> key. You may also execute
    a menu command by pressing the highlighted letter of that command's
    title (name).

    If a menu command is followed by an arrow (), the command leads you
    to another menu. The menu commands show also the shortcuts (the quick
    way) available to select the menu commands. These shortcuts are
    almost function keys or a combination of <Ctrl/Alt> key and the
    highlighted letter of that command's title (name). To close a
    displayed menu item, just press <ESC> or click outside the displayed
    menu area with the mouse pointer.

    Remember to watch the status line on the bottom of the screen. There
    will be shown context sensitive one-line help information about the
    selected menu item, pulled down menu and selected part of the active
    dialog box.

    5 FILE MENU
    ═══════════
    The File menu includes commands for opening new windows, loading and
    saving files, loading and saving a job, changing directories,
    printing the disassembled file, DOS shell, and exiting the program.

    When looking at the file menu commands, you will see the available
    shortcuts to the commands at the same line. These shortcuts list the
    hot keys that can access that command without going through the file
    menu.

    Following shortcuts are available on the file menu:

    ┌────────────┬──────────────────┐
    │  Shortcut  │    Command       │
    ├────────────┼──────────────────┤
    │  F4        │ New              │
    │  F2        │ Save             │
    │  F3        │ Disassemble      │
    │  F7        │ Print            │
    │  F8        │ Change Directory │
    │  F9        │ DOS shell        │
    │  <ALT>+X   │ Exit             │
    └────────────┴──────────────────┘

    5.1 New
    ═══════
    The command New opens another window to show the same already
    disassembled file. Using multiple windows makes disassembling process
    easier. You can see different parts of the disassembled file
    simultaneously. For example, you can see instruction code which
    writes some text on the screen as well as the text itself.

    Theoretically, you may open as many windows as you wish, but
    practically the available memory may restrict you to do so. Another
    restrict may be the size of your screen, but having a monitor with
    EGA/VGA card will be more helpful. You can choose high resolution
    mode to show 43/50 lines with 80 columns width.

    For more information refer to File│Disassemble.

    5.2 Disassemble
    ═══════════════
    The Disassemble command allows you to select an executable file you
    want to disassemble from any drive/directory in your system. This
    command will display a dialog box in which you can select the
    executable file you wish to disassemble. The open file dialog box
    contains a Name input line editor, a file list, a file information
    panel, the standard button Cancel, another action button Open, plus a
    history list attached to the Name input line editor.

    The Name input line editor is to type in the desired file's name with
    the correct path name which is optional. You can also type a drive/
    directory name to show its contents with given file mask. If you type
    in a specific drive name then you should also type in `:' directly
    after that name.

    The file list box shows all files with the given file mask in the
    default (or selected) directory, plus the parent directory and all
    sub directories. Here you may type file's name to select
    incrementally. Use lower case characters to type the file names and
    upper case letters to type the directory names.

    The File information panel describes the selected file. It shows the
    path name, file name, date, time, and size of the selected file. This
    is useful especially when you need to see the size of the file or
    date/time of the last updating.

    NOTE: None of the items on this information panel selectable.

    The dialog box has many standard buttons to perform a desired action.
    Standard buttons, Open and Ok, are available to load and disassemble
    the selected file. Use the standard Cancel button to close the dialog
    box without loading the file. You can close the dialog box by
    pressing the <ESC> key, or clicking on the frame icon at the left top
    of the box with the mouse.

    Choosing the Open or Ok button will load and disassemble the selected
    file. The disassembling time depends on the size of file. After the
    executable file is analyzed and disassembled, a new window will be
    opened to view the disassembled file. Later, you can use the command
    "New" to open extra windows to view the same disassembled file.
    Different windows view the same file independently of each other so
    you can see different parts of the file simultaneously.

    5.3 Save
    ═════════
    The Save command allows you to save the current disassembled file to
    a disk text file. If you have chosen to save automatically via Auto
    Save in the preferences dialog box, this command will use the
    disassembled file's name to build the text file's name, i.e. same
    name with extension "ASM". Otherwise this command will cause a dialog
    box (like the one with Disassemble command) to appear.

    NOTE:
    A warning of existing files will be prompted to you. Your response
    will be performed.

    The dialog box shows all files with extension "ASM" to help you to
    avoid overwriting of the existing files. If you want to save under
    the same name, then nothing can stop you.

    For more information refer to File│Disassemble.

    5.4 Retrieve job
    ════════════════
    This command will restore a previously-saved job from a file saved
    via the File│Save Job menu command. This is useful when you have
    disassembled a file and for some reasons you could not finish the
    job.

    You do not need to start the job from the scratch. Everything you
    have done earlier is now available on the disk file, except the then
    opened windows. You get the job back with only one window. You can
    open as many windows as you wish without any big efforts, you only
    press the key F4.

    It is worthwhile to have this command in Yilmaz DisAssembler.
    Otherwise you have to do the same job repeatedly if you have to
    finish the program before the disassembling process ends.

    5.5 Save Job
    ════════════
    This command will save a whole job into a disk file. Next time when
    you start the job, you do not need to start it from the scratch.
    Everything is saved to the disk file except the present open windows.
    Every time you have a file disassembled in the integrated
    environment, you can open as many windows as you wish without any big
    efforts. The F4 key opens windows.

    This command is useful when you have disassembled a file and for some
    reasons you must finish the job before it is finished. This is why
    this command is available in Yilmaz DisAssembler.

    5.6 Change Directory
    ════════════════════
    The Change Directory command allows you to change the default
    directory you are working. You do this via the Change Directory
    dialog box. The dialog box includes an input line editor, a list box,
    the standard OK and Cancel buttons, and two other buttons (Chdir and
    Revert).

    The Directory Name Input Line Editor is where you specify the desired
    directory path. All accepted directory paths will be saved on the
    history list for later direct accessing.

    The Directory Tree list box enables you to navigate directories by
    using the selecting bar and pressing <RETURN/ENTER>.

    If you are using the keyboard, press <RETURN/ENTER> to make the
    selected directory be the current directory, then choose OK or press
    <ESC> to exit the dialog box.

    The ChDir button changes the current directory once you have selected
    or typed in a directory name.

    The Revert button goes back to the previous directory, as long as you
    have not left the dialog box.

    5.7 Print
    ═════════
    The Print command allows you to print the current disassembled file
    on the installed printer. This software uses the standard device LPT1
    for printing. It does not do any checking of printer types. This
    command will bring up a dialog box to read your printing options.

    The Print dialog box has an input line editor "Header" to type in one
    line text of max length 80 characters as header to print at the top
    of each sheet. You may type in file's name as header.

    The Print dialog box has also two one-digit input (editors) fields to
    type in vertical and horizontal margins of the printing paper. The
    Radio button, "Paper", in this dialog box allow you to choose type of
    paper, make a pause after printing each sheet and choose the paper
    size. This software assumes length of the paper as 62 lines for
    single paper and 65 lines for the fanfold paper. Both have 80
    characters on a line.

    If any input/output error occurs, then an error message will be on
    the status line. The user can correct the error and continue, or
    abort the printing.

    5.8 DOS Shell
    ═════════════
    With the DOS Shell command, you can leave the Yilmaz DisAssembler
    temporarily to perform a DOS command or run another program. When
    selected, the screen will be cleared. You will be in DOS. To return
    to the Yilmaz DisAssembler, type "EXIT" at the DOS prompt.

    5.9 Exit
    ════════
    The Exit command ends the Yilmaz DisAssembler to DOS. Another way to
    execute this command is pressing the hot key Alt-X. It will prompt
    you to save the disassembled file before exiting, if it was changed
    since the last save.

    6 EDIT MENU
    ═══════════
    The Edit Menu includes commands for defining code area, data area, go
    to, insert label and delete label at specified address within the
    disassembled file. The addresses entered should be in hex-numbers and
    of length max 4 digits. The digits in the hex-numbers do not have to
    be upper case. You can use lower or upper case to enter a memory
    address.

    The following shortcuts are available on the Edit Menu:

    ┌────────────┬───────────────┐
    │  Shortcut  │    Command    │
    ├────────────┼───────────────┤
    │  <ALT>+C   │ Code area     │
    │  <ALT>+D   │ Data area     │
    │  <ALT>+G   │ Goto          │
    │  <ALT>+I   │ Insert label  │
    │  <ALT>+L   │ Delete label  │
    └────────────┴───────────────┘

    6.1 Code area
    ═════════════
    The Code area command allows you to define a range of the
    disassembled file as code area. This command will bring up a dialog
    box at the middle of the screen to read your input.

    The dialog box has two identical input line editors to read the
    starting and ending addresses of the code area. Each can accept input
    of max length 4 characters. These characters must be digits, `a'..`f'
    or `A'..`Z'.

    Two standard buttons, OK and Cancel, are also available to accept or
    abort the settings in this dialog box.

    When you are sure that a part of the disassembled file is a code area
    (that is to say: contains code instructions and temporarily a data
    area) use this command to convert it into code area.

    You only specify the starting and ending addresses. The addresses are
    inside the range (the code area starts at the given starting address and
    ends at the given end address). For example, to define a code area at
    the address 202H of the length 1 byte, you enter 202H as starting and
    ending addresses.

    6.2 Data area
    ═════════════
    The Data area command allows you to define a range of the
    disassembled file as data area. This command will bring up a dialog
    box in the middle of the screen to read your input.

    The dialog box has two identical input line editors to read the
    starting and ending addresses of the code area. Each can accept input
    of max length 4 characters. These characters must be digits, `a'..`f'
    or `A'..`Z'.

    Two standard buttons, OK and Cancel, are also available to accept or
    abort the settings in this dialog box. There are also two clusters of
    radio buttons to specify the type and frequency of the declared data.

    When you know that a part of the disassembled file is data area of a
    specified type, i.e. it contains only data that are used in the
    executable file, use this command to specify it as data area. It is
    not necessary the specified area must be a code area. You can split
    an existed data area into two or three different parts of the same/
    different data types.

    You need to specify the starting address, ending address, type of
    data and the frequency of the data area. The addresses are inside the
    range (the Data area starts at the given starting address and ends at
    the given end address). For example, to define a data area at the
    address 202H of the length 1 byte, you enter 202H as starting and
    ending addresses.

    The type together with the frequency of the data area defines the
    length of the data area. The following three data types are
    available:

         ■ Byte is one byte length
         ■ Word is two bytes length
         ■ String of variable length.

    There are three alternatives in the frequency:

         ■ Repeated
         ■ Table
         ■ Duplicate

    Frequency means the same data of a given type is repeated within the
    given area, or it is only a table format. For example in assembly
    language you can either define the variable FileName as

       FileName   DB  12 DUP (0)
                   or
       FileName   DB  'filename.exe'

    The first one corresponds to the Duplicate with Byte type in Yilmaz
    Disassembler's data declaration. The second one corresponds to the
    String data declaration.

    With the string declaration, it does not matter whether you choose
    the frequency of Repeated or Table, the result is the same. Choosing
    the Duplicate alternative will result in data declaration of the
    following format:

       Address/DByteX DB YY DUP ('string')

    Where
      Address  is data area's address in hex-integer (when labels are
               not enabled).

      DByteX   is data area's label (when labels are enabled).
      YY       is the number of repeating of a `string' within the given
               data length.
      `string' is the string from first letter inside the data area until
               next occurrence of the same letter within the given data
               length.

    If you choose the frequency of Repeated with any other data type than
    string, the same data type will be repeatedly declared from the
    starting to the ending address. For example, choosing the frequency
    of Repeated with byte data type in range 120H..13FH, will result in
    data declaration of

      0120H DB 00H
      0121H DB 00H
        .
        .
        .
      013FH DB 00H

    The conventions used in naming of the data areas when the labels are
    enabled, are as following:

     ■ DByteX for data declarations of size 1 byte.
     ■ DWordX for data declarations of size 2 bytes.
     ■ DStrX for string declarations.

    Where X stands for a number (can be of multiple digits) which is
    added to the data name to make difference between data declarations
    of the same type.

    6.3 Goto
    ════════
    The command Goto lets the active window to view the disassembled file
    from the given address. This command will bring up a dialog box at
    the middle of the screen to read your input.

    The dialog box has an input line editor to read the address you wish
    to go to. This editor line will take input of max length 4
    characters. These characters must be digits, `a'..`f' or `A'..`Z'.

    Two standard buttons, OK and Cancel, are also available to accept or
    abort the settings in this dialog box.

    You need only to specify the address of area you wish to move. Of
    course, you enter the address in hex-numbers of length max 4 digits.

    If the given address lies inside a data area which is viewed in one
    line. This command will view the next following line's address at the
    top of the window.

    If the given address lies inside a code instruction which is viewed
    in one line. This command will view the next following instruction at
    the top of the window.

    6.4 Insert label
    ════════════════
    This command enables you to insert the missing labels manually at
    specific address within the disassembled file. Executing this command
    brings up a dialog box in the middle of the screen to read your input.

    For detailed information about this dialog box refer to Edit│Goto.

    6.5 Delete label
    ════════════════
    This command enables you to delete undesired extra labels manually at
    specific address within the disassembled file. Executing this command
    will bring up a dialog box at the middle of the screen to read your
    input.

    For detailed information about this dialog box refer to Edit│Goto.

    7 OPTIONS MENU
    ══════════════
    The Options menu provides the commands that let you customize
    integrated environment's colors, your work preferences, load and save
    the options.

    All the commands in this menu are missing shortcuts to evaluate them.
    The only one way to access them is through the options menu.

    7.1 Colors
    ══════════
    The Colors command allows you to customize the colors of the elements
    of the environment. This command will bring up a dialog box named
    Colors at the middle of the screen.

    The Colors dialog box consists of two list boxes, a text display
    area, the standard OK, Cancel, and Help buttons, and one of the
    following:

         ■ On color and black & white systems, it also contains two color
           palettes.
         ■ On monochrome systems, it contains a set of radio buttons
           instead of the palettes.

    This dialog box is where you can change the colors of different parts
    of this program.

    The Group list box contains the names of the different regions of the
    program that you can customize.

    When you select a group from the Group list, the Item list box
    displays the names of the different views in that region.

    On color and black-and-white systems, you use the Foreground and
    Background palettes to change colors.

    On monochrome systems, you use the Colors set of radio buttons
    systems to change the character attributes.

    On all systems, the display text (above the Help button) shows the
    current color or attribute settings.

    Changes do not take effect on the desktop until you close the Colors
    dialog box by choosing OK.

    7.2 Preferences
    ═══════════════
    This command allows you to choose your preferences in disassembling
    process. You can do so via a dialog box with several clusters of
    check boxes and radio buttons for screen size/mode, program's label
    displaying and auto saving files.

    The standard OK and Cancel buttons are also available to accept or
    not accept the settings of the dialog box.

    If you do not have a mouse device to click on desired alternative,
    you can use keystrokes. Pressing the highlighted letter on the
    desired alternative will select it. You can also use the arrow keys
    to move between items within a cluster and then press <SPACE> to
    select the item. Finally, press the <RETURN/ENTER> when you are
    satisfied with the settings in the dialog box.

    Under screen size/mode you can choose one of two alternatives to
    display the information on the screen:

         ■ 25 lines x 80 columns screen display.
         ■ 43/50 lines x 80 columns screen display.

    If you have EGA/VGA card then you can choose the high resolution
    mode. If you do not have EGA/VGA card, choosing this mode will make
    any changes in your screen display.

    The cluster named Disassembling offers you the ability to display the
    labels instead of memory addresses. In this version, there are only
    two alternatives of labels to display and you can choose both at the
    same time, if you wish so.

    Displaying these labels will also help you to detect wrong code/data
    areas via the comments displayed at the end of the disassembled line.
    If a jump or routine call's label is missing, or points to wrong
    memory address, a message will tell you the label is missing, will be
    shown. The same thing with incorrect data area declaration.

    Selecting JMP/CALL labels means that the memory addresses and object
    codes will disappear from the disassembled text. Selecting both
    labels means the disassembled file will require minimum work to be
    assembled again by any assembler, for example, Turbo Assembler or
    MASM.

    The next cluster AutoSave enables you to save the disassembled file
    and/or the whole job automatically. If you select any of these two
    alternatives, the program will save the disassembled file and/or the
    job on the same directory where the executable file is. The program
    uses the conventional file extension "ASM" with the disassembled
    files and "APP" with the job files.

    7.3 Load Options
    ════════════════
    This command will load the options you saved in the configuration
    file "YD.CFG" last time via the command Options│Save options. The
    loaded options are, your customized colors and your elections to do
    your job.

    7.4 Save Options
    ════════════════
    This command will save your prevailingly chosen options into the
    configuration file "YD.CFG". These saved options are your customized
    colors and your preferences to do your job. You can use the command
    Options│Load options to retrieve these options later.

    8 WINDOW MENU
    ═════════════
    The Window menu contains commands to tile/cascade desktop windows,
    close all windows, resize/move, zoom, close currently active window,
    and cycle forwards/backwards through the windows on the desktop.

    All the windows in this program have all the standard window
    elements, including scroll bars, a close box, and zoom icons.

    Following shortcuts are available on the Window menu:

    ┌────────────┬────────────────┐
    │  Shortcut  │  Command       │
    ├────────────┼────────────────┤
    │ <CTRL>+F5  │  Resize/Move   │
    │ F5         │  Zoom          │
    │ F6         │  Next          │
    │ <SHIFT>+F6 │  Previous      │
    │ <ALT>+F3   │  Close         │
    └────────────┴────────────────┘

    8.1 Tile
    ════════
    Choose Window│Tile to tile all file viewers on the desktop, i.e. to
    arrange them to be seen all on the desktop side by side.

    8.2 Cascade
    ═══════════
    Choose Window│Cascade to stack all file viewers on the desktop, i.e.
    to arrange them to be seen all on the desktop one over another.

    8.3 Close All
    ═════════════
    Choose Close all to put away all windows from the desktop. Closing
    all windows does not mean that the disassembled file is closed or
    resulted in losing of the current work. You can use the command
    File│New to open new window later on to view the currently
    disassembled file again.

    8.4 Resize/Move
    ═══════════════
    Choose this command to change the size or position of the active
    window. If you press <SHIFT> while you use the arrow keys, you can
    change the size of the active window. Once you've adjusted its size
    or position, press <RETURN/ENTER>.

    If a window has a Resize corner, you can drag that corner to resize
    the window.

    When you choose Window│Resize/Move, the active window moves in
    response to the arrow keys. Once you've moved the window to where you
    want it, press <RETURN/ENTER>.

    You can also move a window by dragging its title bar with the mouse.

    8.5 Zoom
    ════════
    Choose Zoom to resize the active window to the maximum size. If the
    window is already zoomed, you can choose this command to restore it
    to its previous size.

    You can also double-click anywhere on the window's title bar (except
    where an icon appears) to zoom in or out in the window.

    8.6 Next

    8.7 Previous
    ════════════
    Choose Previous to cycle backwards through the windows on the desktop.

    8.8 Close
    ═════════
    Choose Close to close the active window. This does not mean that the
    disassembled file is closed or resulted in losing of the current work.
    You can use the command File│New to open new window later to view the
    currently disassembled file again.

    You can also click the Close box in the upper left corner to close a

    10 WINDOWS
    ══════════
    Yilmaz DisAssembler Version 1.1 (TM) uses the windows to present the
    disassembled file's contents and on-line help about this software on
    the screen. Many windows can be on the screen when they can overlap
    each other. Each window in this software has following parts:

         ■ Shadowed frame around the window.
         ■ Title at the middle of upper frame side.
         ■ Frame icons around the title.
         ■ Two scroll bars.
         ■ Application surface where the information is displayed.

    All the windows in this software can be moved or resized by mouse
    clicks/drags or arrow keys. They also can be zoomed and closed by
    mouse clicks or keystrokes. You can use the arrow keys to scroll up/
    down the displayed information. They use different text attributes
    (colors) to view the information on the screen. For example, the
    disassembled file is viewed in two different colors, Yellow
    (foreground) on Blue (background) for code instructions area and
    Yellow (foreground) on Cyan (background) for data area.

    All window colors can be customized via the command Options│Colors.
    The following commands (or reacts to keystrokes) are available in
    each window:

    ┌─────────────┬────────────────────────┐
    │ Keystroke   │ Action                 │
    ├─────────────┼────────────────────────┤
    │ <UP>        │ Move up one line       │
    │ <CTRL>+E    │ Move up one line       │
    │ <DOWN>      │ Move down one line     │
    │ <CTRL>+X    │ Move up one line       │
    │ <RIGHT>     │ Move right one column  │
    │ <CTRL>+D    │ Move right one column  │

    │ <CTRL>+S    │ Move left one column   │
    │ <PGUP>      │ Move one page up       │
    │ <CTRL>+R    │ Move one page up       │
    │ <PGDN>      │ Move one page down     │
    │ <CTRL>+C    │ Move one page down     │
    │ <CTRL>+PgUp │ View top of file       │
    │ <CTRL>+PgDn │ View bottom of file    │
    │ <HOME>      │ Show from first column │
    │ <END>       │ Show until last column │
