I am currently running GNU Emacs 18.55.3 and trying to define the function keys on a SUN-3 terminal, and am finding it impossible to properly define some of the Left function keys (L6, L9, F1, and more). How can I do this? I am currently trying to use the `define-key' command: (global-set-key "\e[200z" 'find-file);L9:VISIT NEW FILE and am having no success what so ever. The "special" function keys are not being redifined, while the other function keys are. If there are any old postings or notes on this subject, please send them to me. Any help is greatly appreciated. Andrew Montgomery zjam0b@apctrc.trc.amoco.com

If you want to see if you can use it, you can simply edit your .emacs and type in the global-set-key, but to enter the sequence, type the opening quote, C-q (or if flow control is a problem, use "M-x quoted-insert" if you must) then type the function key itself and the closing quote. If the window system isn't trapping that key, you should get the proper string in quotes. (then, if you want, replace the literal escape with "\e" -- shouldn't matter.) Deven -- Deven T.

Just tried this. The escape sequence does get inserted into the file. I then tried to evaluate the command, and emacs complains that I'm using an invalid prefix key. Jim

The problem is that ESC-[ is bound to the function backwards-paragraph already, so it can't be the beginning of a longer sequence at the same time. You have to say: (global-unset-key "\e[") before the global-set-key. If you use sunwindows, I recommend that you use emacstool instead; it encodes the function keys differently and compatibly. If this isn't installed at your site, it should be the file $EMACS/etc/emasctool. (Actually, I recommend you obtain and use the window system named X in preference to any of this). Otherwise, look at the file $EMACS/lisp/term/sun.el; here's the relevant bit: (defvar sun-esc-bracket nil "*If non-nil, rebind ESC [ as prefix for Sun function keys.") Basically, this means that, if you say: (setq sun-esc-bracket t) in your .emacs file, the function keys on the Sun will all be enabled for you (modulo .ttyswrc). (Under emacstool, they are all enabled, and emacs sees sequences starting with C-x *). They dispatch through the keymap sun-raw-map. See sun.el, and $EMACS/etc/SUN-SUPPORT. This ought to be recurrent comp.emacs posting number 1. Maybe it could be the only posting ever in comp.emacs.sun, with an expire: never. :-) -- /jr, nee John Robinson Life did not take over the globe by combat, jr@bbn.com or bbn!jr but by networking -- Lynn Margulis

That means that you have some function assigned to a sequence which is part of that full sequence. In this case, almost certainly the culprit is ESC [ -- so include (global-unset-key "\e[") before you try the global-set-key's... Deven -- Deven T.
