[Additional notes and tips on next page]
Insert Mode versus Overtype Mode
--------------------------------
In insert mode, all characters typed are INSERTED before the cursor. The
ENTER key splits the line and BACKSPACE can re-join lines.
In overtype mode, characters "type over" what was on the screen before.
Overtype mode also disables the automatic line SPLIT / JOIN available in
insert mode. Use ^N(split) and ^J(join) to manually split and join
lines while in overtype mode.
Keyboard emulation
------------------
The easiest way to control the cursor in Visual Edit mode is to use your
cursor keys. Most popular terminal programs provide some sort of
keyboard emulation. Unfortunately, this emulation is either incomplete
or requires you to go through an involved configuration process.
ProStory also supports the "Doorway" keyboard mode of Qmodem.
The WordStar* command set was chosen as a control-character command set
because it can function on virtually any keyboard and with any terminal
emulation mode. It also has the advantage of leting you keep your
fingers on the "home" keys while moving the cursor around.
Function Keyboard Codes Recognized Doorway Codes

or <esc> A <nul> H
Cursor down . . . . . . . . . . ^X
or <esc> B <nul> P
Cursor right. . . . . . . . . . ^D
or <esc> C <nul> M
Cursor left . . . . . . . . . . ^S
or <esc> D <nul> K
Word right. . . . . . . . . . . ^F <nul> t
Word left . . . . . . . . . . . ^A <nul> s

or <esc> r <nul> I
Page down. . . . . . . . . . . ^C
or <esc> q <nul> Q
Insert mode toggle . . . . . . ^V
or <esc> n <nul> R
In this table, the symbol <esc> means any one of these character code
sequences:
chr(27)
chr(27) [
chr(27) [ O
The symbol <nul> means chr(0) or an ascii NUL. These codes correspond
directly to the IBM extended scan codes produced by the corresponding
keyboard keys. These codes are used if your terminal program supports
"Doorway" mode.
This provides support for a wide variety of keyboard emulations.
