RI(9)/VEDIT and VEDIT PLUS - Multiple File Editing/
M(H) !Display header
YT\
With VEDIT and VEDIT PLUS you can easily edit two, three or more files at the
same time. Each file can be of any size and can optionally be displayed in its
own window. You can also display different parts of one file in separate
windows.
Although you can select additional files to edit using the {FILE} sub-menu
and split the screen into windows with the {WINDOW} sub-menu, several
built-in keystroke macros simplify these processes.
<ALT-O> Prompts you for the next file to edit and automatically selects an
unused edit buffer in which to simultaneously edit this file.
<ALT-Y> Same as <ALT-O> except it also splits the current window into two
horizontal windows.
<ALT-T> Toggles between the files/windows created with <ALT-O> or <ALT-Y>.

I/Many times you simply want to edit a new file after saving the current file,
i.e. you don't need to simultaneously edit the two files. You can edit a new
file by pressing <ALT-N>. For example, you are currently editing the file
"DEMO.TXT". To save this file and begin editing the file DEMO2.TXT press
<ALT-N> and at the filename prompt enter "DEMO2.TXT". If you modified
DEMO.TXT, you will be prompted whether to save or abandon this file.

I/If you are not exactly sure of the filename you can use VEDIT's "point and
shoot" file selection. When prompted for a filename simply press <Enter> to
see all files in the current directory or enter a "filter" such as "*.txt" to
select only the files ending in ".TXT".
Experiment with the "point and shoot" by pressing <ALT-N> again to select
a new file to edit. Note the "help" line on the bottom of the screen during
point and shoot. --- Press <ESC> to continue ---/

I/You are again editing the single file "DEMO.TXT". To simultaneously edit
a second file press <ALT-O>. At the prompt enter the name of the file to
edit. For example, enter "DEMO2.TXT" and press <Enter>.
You are now editing the file DEMO2.TXT. The letter "A" in the top-left of the
status line indicates that this file is being edited in buffer "A".

I/Press <ALT-T> to toggle between the files being simultaneously edited.
Notice how the name of the active file is displayed on the status line.
(This demo uses buffer "1" to display the instructions; therefore <ALT-T>
also toggles to this text. Normally, when you aren't running this demo,
just the current file being edited would be displayed on the screen.)

I/It is usually easiest to switch between files by repeatedly pressing <ALT-T>.
However, if you know the name of its corresponding buffer, you can switch
directly to a file by pressing <F4> and its buffer name. Press <F4> and "A"
to switch to buffer A; press <F4> and <Enter> to switch to the main buffer.
Feel free to experiment. An additional (third) file you can simultaneously
edit is "DEMO8.TXT". --- Press <ESC> to continue ---/

I/You are again editing the single file "DEMO.TXT". To simultaneously edit a
second file, but also display it in its own window press <ALT-Y>. At the
prompt enter the name of the file to edit. For example, enter "DEMO2.TXT".
Notice how the screen has been split in half and that the status line
indicates you are editing "DEMO2.TXT".

I/Press <ALT-T> to again toggle between the files being simultaneously edited.
This time, however, you are also toggled from one window to another. Notice
how the "WINDOW" message in the active window is highlighted. Normally, the
cursor will be blinking in the active window.
Feel free to experiment.

I/With a mouse, you can easily switch between windows by moving the mouse
anywhere within the desired window and clicking the left button.
When you click the left button in a non-active window, VEDIT switches to
that window. When you click the left button in the active window, VEDIT
moves the editing cursor to the position of the mouse cursor.

I/To help remind you which files are being edited, enter the {HELP} sub-menu
(<ALT-H>) and select "Edit Buffers". This displays the name of each file with
its associated window and "buffer" name. (Buffers 1 & Z are used by the demo.)
You can use <ALT-T>, <F4> or {FILE, Buffer Switch} to switch between files.
<F4> is a "hot key" (keystroke macro) for the function {FILE, Buffer Switch}.

I/You are again editing the single file "DEMO.TXT". To display the file in two
vertical windows press <ALT-V>. Press <PgDn> a few times. Notice how only
the current window scrolled down. You can view different parts of a file at
the same time.
Press <PgUp> again until both windows show the same text. Make some edit
changes. Notice how both windows update at the same time.

I/Press <PgDn> again a few times. Now press <ALT-F4>. At the prompt press
"0". Notice how this has switched you to the other window on the same file.
You can, of course, edit in this window too.
Press <ALT-F4> and then just <Enter> to switch back to the default "@" window.
<ALT-F4> is just a "hot key" (keystroke macro) for {WINDOW, Switch}. You can
press <ALT-F4> or use the {WINDOW} sub-menu to switch windows.
