I just got the latest (5.19) version of tcsh and I have problems binding SUN function keys. In the following example, I want to bind R7 to beginning-of-line: % bind function-key-prefix M-[ % bind beginning-of-line X-214z bad key specification -- unknown name "" The man page says: If given two arguments bind binds the function (first argu- ment) to the given key (second argument). The key may be: the direct character or a caret-<letter> combination, which is converted to control-<letter>; M-<letter> for an escaped character; or X-<string> for a function key. For the last of these, the function key prefix must be bound to the func- tion "extended-key-prefix" and the string specified to the bind command must not include this prefix. Notice how it says "M-<letter>" and "X-<string>". I understand this to mean that the M- prefix can be followed only by a single letter but that the X- prefix can be followed by a string. I believe the documentation is wrong but, anyhow, is there a workaround? I know about .ttyswrc mapping, but I can't use that on a raw console. -- Martin Boyer mboyer@ireq-robot.hydro.qc.ca Institut de recherche d'Hydro-Quebec mboyer@ireq-robot.uucp Varennes, QC, Canada J3X 1S1 +1 514 652-8136

It appears to be an error in the documentation. The clue is in the
output from bind, where the arrow keys are listed as "F-A", "F-B", etc;
they generate the sequences ^[[A, ^[B, etc.
My F9 key generates ^[[20~, so I tried:
> bind downcase-word F-20~
This worked fine.
It seems that bind X-<?> is equivalent to bind ^X<?>; it just binds the
keystrokes prefixed by ctrl-x.
