Gnu Emacs 18.53 and X11R3: The keypad key `.' on a vt100 keyboard emits the escape sequence ``ESC O n'' (3 hex. characters). In the non-X11 emacs (`-nw' switch) this code is bound to `delete-char'. In xemacs however, this doesn't work. $TERMCAP is set to vt100. Even loading of `term/vt100.el' and of `keypad.el' doesn't help. Interestingly, typing `Cntl-Q' and then the keypad key `.' inserts a `.' into the buffer. The function `delete-char' is executed if I enter the escape sequence `ESC O n' (3 key strokes) "on foot". So it seems that the software binding does work, but not the mapping of the keypad key `.' to the above escape sequence. What am I missing? Thanks in advance, -- Georg Wittig GMD-Z1.BI P.O.

On the HDS-200, the up-arrow key is bound to the key sequence ESC [ A. I have tried (define-global-key "\e[A" 'previous-line) which doesn't work-- emacs is still reading ESC [, doing the (backward-paragraph) command, and then printing the letter A. So, 1) Is the define-global-key okay? 2) If the problem is the same one as the vt100 question, how does one get emacs to take the 3-character sequence? (e.g., if it's a termcap problem, it'd be really nice to know what in the termcap to fix, though I suppose that would be a question for comp.terminal.) Thanks in advance, David Yang d-yang@cs.columbia.edu

This is a frequently enough asked question that it should probably be
addressed briefly here again.

Depends on whether you happen to have that function doing the right
thing. There is no define-global-key in GNU Emacs as distributed;
perhaps you meant global-set-key?
In order to access the rest of the binding, if you do have M-[ A
correctly bound, Emacs needs to follow key prefixes to it. Since
backward-paragraph is still bound to M-[ it can't do that. A
global-unset-key of M-[ will enable Emacs to look further for the A,
and hence the command to execute.

Which vt100 question? Anyway, you can
(setq term-setup-hook 'enable-arrow-keys)
in .emacs to have the arrow keys enabled after the term/$TERM.el file
is loaded. See emacs/lisp/term/*.el and emacs/lisp/keypad.el for more
information.
