> The issue here is that the dead keys themselves > are producing the wrong characters. No. If someone without diaeresis key uses the double quote, and attaches dead_diaeresis to it, she probably wants that double quote when it is followed by a space. When programming one needs quotes etc. When writing text one needs a-umlaut and c-cedilla etc. Very few people need a lone diaeresis. I do not mind if most people would need an additional keystroke to obtain that. > the dead_* are wrong, and I can't change them with a keymap, afaik? Yes, you can. Linux keyboard handling is very flexible. You can change the table of compose definitions with loadkeys, and there is no restriction of what is combined with what. You can also make any symbol into a dead symbol. Example: % loadkeys plain keycode 53 = 0x0d2f compose '/' 'o' to '\370' % This makes the slash (on my keyboard) into a dead slash: when followed by an o I get the Danish oslash (ø), and otherwise it remains a slash. Explanation of the loadkeys input: The first line makes unadorned [no Shift, Ctrl, Alt] slash (on my keyboard the key with keytop / has keycode 53 as showkey tells me) into a dead ASCII slash. The 0d part is for "dead". The 2f part is hex for the ASCII slash (octal 057). The combine statement adds a combination to the compose table. (Maybe it was there already - didnt check.) For 2f and 370, see ascii(7) and iso_8859-1(7).

Re: [PATCH] Dead keys
From [EMAIL PROTECTED] Tue May 1 20:05:26 2001 Normally, you wouldn't notice this too much, since the compose rules are set up in such a way that you can use the dead keys to compose what you would expect, anyway. However, if you were to press a dead key and then space, or some un-composable key (to get the dead key character by itself), you would get the wrong character. Instead of '¨' (ISO 8859-1 decimal 168: DIAERESIS), you would get '"' (ASCII decimal 34); instead of '´' (ISO 8859-1 decimal 180: ACUTE ACCENT), you would get '\'' (ASCII decimal 39); and instead of '¸' (ISO 8859-1 decimal 184: CEDILLA), you would get ',' (ASCII decimal 44). I took the liberty of creating a patch that changes this in keyboard.c, and also adds compose rules to defkeymap.map so they can be used properly. If there is some reason why this shouldn't be applied, I'd like to know what, since this makes my console life easier. :) I think the main reason why it shouldn't be applied is that it changes something.

[PATCH] Dead keys
Hello.
I've long been bothered by the fact that 3 of the 6 "dead keys" in the
kernel are actually mapped to the wrong characters. Now, I realize that
there might be some deliberate reason for this, since it's such an
obvious annoyance and since they all fit in US ASCII the way it is now.
Also, I've noticed that it is the same way in X11, independent from
this. I'd like to know the reasoning, if there is one.
Normally, you wouldn't notice this too much, since the compose rules
are set up in such a way that you can use the dead keys to compose what
you would expect, anyway. However, if you were to press a dead key and
then space, or some un-composable key (to get the dead key character by
itself), you would get the wrong character. Instead of '¨' (ISO 8859-1
decimal 168: DIAERESIS), you would get '"' (ASCII decimal 34); instead
of '´' (ISO 8859-1 decimal 180: ACUTE ACCENT), you would get '\'' (ASCII
decimal 39); and instead of '¸' (ISO 8859-1 decimal 184: CEDILLA), you
would get ',' (ASCII decimal 44).
I took the liberty of creating a patch that changes this in keyboard.c,
and also adds compose rules to defkeymap.map so they can be used
properly. If there is some reason why this shouldn't be applied, I'd
like to know what, since this makes my console life easier. :)
Thanks.
(Patched against 2.4.3, but it applies to 2.4.4 too. Just tested it.)
