bind C-å o C-e

bind C-å o C-e

[A. Drosos]

Hi

I'm using emacs 22.0.50.1 build from source on a Linux from Scratch box. I'm
also editing text documents in the greek language. On the console, I can
switch between greek/english with LeftAlt-Shift and still be able to use the 
regular C-e and similar sequences to move around my document. This does not
happen in X-windows. The message I get for C-å (for example) and similar keys, 
is that they are undefined.

I tried to google for an answer to this problem and tried a great variety of
possibilities in my .emacs file to bind C-å back to C-e, with no success.
I'm sure there are many users who have come up with something similar in
their own native languages. Being a newbie with emacs I may not even be
using the correct search words! I would greatly appreciate pointers in the
right direction.

TIA

Have you also tried to bind C-å to the same command that C-e is  
performing?


You could bind global-set-key to some key-binding. Interactively you  
can try to bind C-å to move-end-of-line. Then press: C-x ESC ESC C-a  
C-k C-g (repeat-complex-command, move-beginning-of-line, kill-line,  
keyboard-quit). After that position the cursor at some proper place  
in .emacs and type C-y C-x C-s (yank, save-buffer).

This is going to be a major pain, as all the Greek characters,
accented, lowercase, and uppercase will have to grow mappings and
then these mappings will quickly get out of sync if you remap
some English-based key sequence from within Emacs with
global-set-key or local-set-key.

Unfortunately, I don't have a good solution for the OP's problem,
even though I'm also using Emacs with:

    (set-language-environment "Greek")

in my ~/.emacs file.

Giorgos

it could be that this is not so much an emacs issue, but rather an
X-related issue. what happens in programs other than emacs?

I see the same thing with emacs-23 (the unicode-2 branch from cvs).

xev(1x) shows this for C-α:

,----(xev keypress event)
| KeyPress event, serial 30, synthetic NO, window 0x1000001,
|     root 0x4c, subw 0x0, time 440539587, (134,152), root:(760,179),
|     state 0x4000, keycode 66 (keysym 0xffe3, Control_L), same_screen YES,
|     XKeysymToKeycode returns keycode: 37
|     XLookupString gives 0 bytes: 
|     XmbLookupString gives 0 bytes: 
|     XFilterEvent returns: False
| 
| KeyPress event, serial 30, synthetic NO, window 0x1000001,
|     root 0x4c, subw 0x0, time 440539762, (134,152), root:(760,179),
|     state 0x4004, keycode 38 (keysym 0x61, a), same_screen YES,
|     XLookupString gives 1 bytes: (01) ""
|     XmbLookupString gives 1 bytes: (01) ""
|     XFilterEvent returns: False
`----

vs this for just α:

,----(xev keypress event)
| KeyPress event, serial 30, synthetic NO, window 0x1000001,
|     root 0x4c, subw 0x0, time 440536069, (134,152), root:(760,179),
|     state 0x2000, keycode 38 (keysym 0x7e1, Greek_alpha), same_screen YES,
|     XLookupString gives 2 bytes: (ce b1) "α"
|     XmbLookupString gives 2 bytes: (ce b1) "α"
|     XFilterEvent returns: False
`----

Apps like rxvt-unicode see the “state 0x4004, keycode 38 (keysym 0x61 a)”
and generate a C-a, but apps like emacs and gvim end up with keysym 0x7e1
and end up inserting a α or complaining that C-α isn’t bound.

I can only presume that emacs, et al are setting filters and such to track
the modifier keys themselves rather than relying on XLookupString(3x) and
friends to do it.  Or that by filtering out the modifier keys XLookupString(),
et al return different results.

AFAICS emacs will require a patch to fix this issue.  Until then you
can run it in a terminal window (rxvt-unicode is my favourite for
running « emacs -nw », but xterm is also good) if the current situation
gets in the way.  I use emacs-23 and emacs-22 quite a lot over ssh; it is
just as useful as running it in X11-native mode, given an adequate term.
