║ NAVIGATING THE MENUS ║
╚════════════════════════════════════════════╝
■ Press `F8` Contents
Besides the point-and-shoot hypertext features
described under "Quick Commands", Think & Do
programs provide other features to make reading
text more convenient. To select any item from
within the menubar:
[] Press `F10` to access ~Menubar~
[] Use your arrow keys to `highlight`
the appropriate item
[] And then press `ENTER` when ready
:FILES_MENU
■────────────────────────────────────────────■
■ Press `F8` Contents
The ~Files~ menu lets you select files to
view, drop to DOS, or exit the program
altogether.
The `Open` item displays a dialog with three
lists:
[] Files, Directories, and Drives
Each of these is a sorted list. Entries can
be selected by using your `ARROW` keys, or by
typing the first letters of the entry. When
the appropriate entry is highlighted, press
`ENTER`. To move from one list to another,
press your `TAB` key.
The Open `Files` list displays files in the
current directory. To view a file, select
its name from the list. If a program --
rather than a text file -- is selected, the
program is launched.
To change the current file mask, press `TAB`
to move to the `Directories` list and select
the ". <current>" entry.
The Open `Directories` list displays sub-
directories. To change to a subdirectory,
select its name from the list.
The Open `Drives` list displays available
drives. To change to another drive, select
its letter.
The `Dos Shell` item temporarily returns you
to your operating system without exiting the
application.
The `Exit` item closes your application, and
returns you to DOS. When you exit the appli-
cation, the program will automatically save
your current hypertext application so that
later, when you return to the program again
your hypertext application will be reloaded...
it will appear as though you had never left.
:CONTENTS_MENU
■────────────────────────────────────────────■
■ Press `F8` Contents
The ~Contents~ menu will display headings (or
labels) found in a text in two different ways:
[] The `Table` of Contents lists the
~headings~ (labels) sequentially.
This menu will also highlight the
name of the heading currently in
view, lending a "you are here"
affect.
[] The `Index` of Contents lists the
headings sorted alphabetically. The
index does not "autoseek" the current
heading, but remains at the heading
selected when it was last used.
To return to a previous screen after using
either menu, press `BACKSPACE`, or
`SHIFT - F9` for the ~Screen History Menu~.
:NAVIGATE_MENU
■────────────────────────────────────────────■
■ Press `F8` Contents
The ~Navigate~ menu leads to these submenus:
[] Goto_Menu*
[] Jump_Menu*
[] Screen_Menu*
:Goto_Menu
The ~Goto~ menu is a hypertext fastlane;
instead of bothering with lists, readers
can input a heading (label) or file names,
or page or row numbers directly. This is
handy for the reader who already knows the
text well.
`Note`: The Goto `File` item can also be
used to launch external programs that need
command line arguments. Just type the name
of the program (including the .EXE or .COM
extension) followed by any parameters as you
would use them at a DOS prompt.
:Jump_Menu
The ~Jump~ command assumes your cursor is on
or next to the name of a ~heading~ (label).
Pressing `ENTER` is another way to make this
type of jump. The Jump `File` item assumes
the cursor is on or next to the name of a
file: just as if the words were "quoted".
The `Next_star` and `Prev_star` items move
the cursor to the next or previous asterisk.
:Screen_Menu
The ~Screen History~ menu specifies the last
line the cursor was on for the ~last 128
screens viewed~. To return to a prior screen,
simply ~select~ a line from the `History` list.
If the file is not already loaded, the program
will try to load it for you.
Screen `Insert` adds the current line to the
`History` list, just as if you had jumped or
scrolled from it. Screen `Insert` is the
hypertext answer to bookmarks.
The `Back_track` and `Retrack` items allow you
to move quickly along the screen `History`.
After you have back tracked to review a
screen, you can use Retrack to resume your
reading. The screen `History` list works like
an infinite loop: if you Backtrack or Retrack
long enough, ~you will always return to where
you began~.
:SEARCH_MENU
■────────────────────────────────────────────■
■ Press `F8` Contents
The ~Search~ menu provides for two types of
searches. The first, called `Find text`, is
the conventional type of search used by most
any hypertext application: ~input a word,
phrase, or text string,~ press `ENTER`, and
the program ~jumps you to the next occurrence~
of that word, phrase, or text string in your
current file.
Additionally, this program offers a `Global`
search feature. This feature will ~quickly
find every occurrence~ of the given word or
string in a file, ~compile~ a `Hit List` of
the lines containing that word or string, and
then display the list.
You can then scan the `Hit List` for the lines
you want, and jump to them on demand. The
`Hit List` remains available until the next
`Global` search, so you can ~jump back and
forth~ between ~finds~ as needed.
~When searching for text~, this program uses
the same upper/lower case matching used by
major word processing programs. UPPERCASE
letters only match other UPPERCASE letters,
while lower-case letters match UpperCase and
lower-case letters.
~To search for a whole word~, type a space
before and after the word. A single leading
or trailing space can also be used to find
a prefix or suffix.
