HELP VEDCIFER Aled Morris, December 1985
lib vedcifer
This command loads a library file to convert VED to work with the Cifer
2634 range of terminals by downloading machine code routines into the
terminals own CPU. While it is loading, the screen will clear, and the
"downloading" arrow will appear. After downloading, the "okay" tick will
be displayed, followed by the POP-11 prompt.
A preliminary set of mappings from keys to functions has been
implemented. For exact information on the current state of the package
do
showlib vedcifer
Also, the file HELP *CIFERKEYS provides a printable 'map' of the key
settings for the Cifer terminal, which can be attached to the keyboard
for easy reference.
The package includes a procedure VEDCIFER which is invoked automatically
when the libarary file is loaded. It sets up the function keys on the
Cifer to transmit character sequences of the form
<ESC> ? <character>
The basic mode of operation is very similar to the use of the Visual 200
terminal with VED. Function Key mappings are described at the end of
this file.
Instead of loading LIB CIFER, you may be able to run a saved image:
UNIX: pop11 -vedcifer
VMS: pop11 /vedcifer
Whether these images are available will depend on the system management.

--- Cifer Keys --------------------------------------------------------
The function keys are those keys on the top row of the keyboard, while
the keypad keys are on the right.
The numeric keypad keys work as on the Visual 200 - moving the cursor in
8 directions, except for key 5, which puts the cursor on the middle of
the current line. Pressing <ESC> then a key causes a large jump instead
of just one character.
Remaining keypad keys:
ENTER key -- go to command line, and clear it
"-" key -- redo command on command line
"'" key -- switch between command line and edit window
"0" key -- move cursor a word to left
"." key -- move cursor a word to right
The arrow keys move the cursor a screenful at a time.
Notice that the SKIP key is defined as CHARDELETE, duplicating the
function of the delete key, which is in an odd location at the far right
of the keyboard !
--- Other Key Sequences -----------------------------------------------
There are alternatives to using the function keys. Many of the
operations can be performed equivalently by typing control characters or
key sequences.
You can find which procedure is currently mapped onto a key or key
sequence by VED if you give the command
<ENTER> hk
This will ask you to press the key or key sequence. If there is a
corresponding procedure its name will be printed on the command line. If
nothing is printed then you have started the beginning of a key sequence
which is not complete. You can try completing the sequence in various
ways.
--- Control Characters ------------------------------------------------
Some of the VED functions can be achieved by control characters, i.e.
hold down the CTRL button and press a key. (CTRL-A is represented below
as ^A) Some codes are listed as being "not used". This is not the same
as undefined (undef) - VED (or the host operating system) ignores the
"not used" codes.
^@ not used ^P DOTDELETE
^A SCREENLEFT ^Q not used
^B WORDLEFT ^R WORDRIGHTDELETE
^C not used ^S not used
^D _LMR ^T CHARUP
^E CLEARTAIL ^U CLEARHEAD
^F WORDRIGHT ^V CHARDOWN
^G STATUSSWITCH ^W WORDLEFTDELETE
^H (BS key) CHARDELETE ^X not used
^I (TAB key) tab ^Y not used
^J (LF key) NEXTLINE ^Z TEXTRIGHT (Not if ^Z is "suspend")
^K SCREENUP ^[ (ESC key) see below
^L SCREENDOWN ^\ undef
^M (RETURN key) DOCR ^] LINEDELETE
^N CHANGECASE ^^ undef
^O not used ^_ REDOCOMMAND
All the other codes are printing characters, except delete (character
\?, ASCII 127), which is defined as CHARDELETE.
--- Escape Sequences --------------------------------------------------
Several commands may be given by typing the <ESC> key followed by
another key. These look arbitrary, but the sequences are in fact mostly
those produced by function keys. You can also type them directly
yourself. Note that the upper case letters, e.g. the `H` key in <ESC> H
need the SHIFT key to be pressed.
Check with the ENTER HK command, as described above, before altering the
function of any code sequence.

--- <ESC> ? Sequences -------------------------------------------------
The function and KeyPad keys are programmed to return sequences of the
form <ESC> ? <code>. See the key tables (below) for details.
