zile-2.2.24 doesn't distinguish between ^h (help function) and ^? (backspace), even when backspace is configured to send ascii del. I found a small patch online (http://www.mstevens.org/code/zile-backspace.html) that fixes this: $ cat zile-2.2.24-ctrl-h.patch --- src/term_ncurses.c.orig 2007-05-29 21:27:53.000000000 +0200 +++ src/term_ncurses.c 2007-05-29 21:28:41.000000000 +0200 @@ -155,6 +155,7 @@ case KEY_DC: /* DEL */ return KBD_DEL; case KEY_BACKSPACE: /* BS */ + return KBD_CTRL | 'h'; case 0177: /* BS */ return KBD_BS; case KEY_IC: /* INSERT */ Reproducible: Always Actual Results: keycombo ctrl-h h doesn't produce help text, but a 'h' in the scratch buffer.

C-h and backspace work for me (on the Linux console). With your patch applied, backspace doesn't work anymore ... See also /usr/share/zile/FAQ: 2.9. The `C-h' key is bound to <BS>/<DEL>; help doesn't work.
In case you observe the problem within an xterm, you may also look at <http://www.ibb.net/~anne/keyboard/keyboard.html#terminfo> for possible solutions. (In short: "infocmp" should show kbs=\177. If it shows kbs=^H then you have a problem with terminfo.)
