\*E uses fairly standard termcap fields for most things.
I invented the cursor shape names and some of the function key names,
but other than that there should be few surprises.
:co#: number of columns on the screen (chars per line)
:li#: number of lines on the screen
:ce=: clear to end-of-line
:cl=: home the cursor & clear the screen
:cm=: move the cursor to a given row/column
:up=: move the cursor up one line
:am: auto margins - wrap when char is written in last column?
:xn: brain-damaged auto margins - newline ignored after wrap
:al=: insert a blank row on the screen
:dl=: delete a row from the screen
:cd=: clear to end of display
:ic=: insert a blank character
:sr=: scroll reverse (insert row at top of screen)
:ti=: terminal initialization string, to start full-screen mode
:te=: terminal termination, to end full-screen mode
Optional strings received from the keyboard
:kd=: sequence sent by the <down arrow> key
:kl=: sequence sent by the <left arrow> key
:kr=: sequence sent by the <right arrow> key
:ku=: sequence sent by the <up arrow> key
:kP=: sequence sent by the <PgUp> key
:kN=: sequence sent by the <PgDn> key
:kh=: sequence sent by the <Home> key
:kH=: sequence sent by the <End> key
:kI=: sequence sent by the <Insert> key
Originally, termcap didn't have any names for the <PgUp>, <PgDn>, <Home>,
Although the capability names shown in the table above are the most common,
they are \fInot\fR universal.
SCO Xenix uses :PU=:PD=:HM=:EN=: for those keys.
Also, if the four arrow keys happen to be part of a 3x3 keypad,
then the five non-arrow keys may be named :K1=: through :K5=:,
so an IBM PC keyboard may be described using those names instead.
\*E can find any of these names.
Optional strings sent by function keys
:k1=:...:k9=:k0=: codes sent by <F1> through <F10> keys
:s1=:...:s9=:s0=: codes sent by <Shift F1> ... <Shift F10>
:c1=:...:c9=:c0=: codes sent by <Ctrl F1> ... <Ctrl F10>
:a1=:...:a9=:a0=: codes sent by <Alt F1> ... <Alt F10>
Note that :k0=: is used to describe the <F10> key.
Some termcap documents recommend :ka=: or even :k;=: for describing
the <F10> key, but \*E doesn't support that.
Also, the :s1=:..., :c1=:..., and :a1=:... codes are very non-standard.
The terminfo library doesn't support them.
Consequently, if you're using the terminfo library then you might as well
add -DNO_SHIFT_FKEY to your CFLAGS setting.
Optional fields that describe character attributes
:so=:se=: start/end standout mode (We don't care about :sg#:)
:us=:ue=: start/end underlined mode
:md=:me=: start/end boldface mode
:as=:ae=: start/end alternate character set (italics)
:ug#: visible gap left by :us=:ue=:md=:me=:as=:ae=:
Optional fields that affect the cursor's shape
The :cQ=: string is used by \*E immediately before exiting to undo
the effects of the other cursor shape strings.
If :cQ=: is not given, then all other cursor shape strings are ignored.
:cX=: cursor used for reading EX command
:cV=: cursor used for reading VI commands
:cI=: cursor used during VI input mode
:cR=: cursor used during VI replace mode
If the capabilities above aren't given, then \*E will try to use the
following values instead.
:ve=: normal cursor, used as :cQ=:cX=:cI=:cR=:
:vs=: gaudy cursor, used as :cV=:
Here's the termcap entry I use on my Minix-ST system.
