Mapping alt to altgr

Mapping alt to altgr

[Daniel Aarno]

Hi, I tried to map left alt to altgr (right alt) in emacs without success. I 
tried using xmodmap to do this by changing alt_L from mod1 to mod2 but emacs 
didn't like that. Doing that makes left alt work as altgr in all other xprogram 
such as xterm and even XEmacs. However, running emacs both left alt and altgr 
now only gives me the beeep when I try to use them. I'm on a Solaris 9 OS with 
sun swedish key-board.

Greatful for any insight

You know 'xmodmap -pm'?

You know xev that tells you a key's keysym and keycode?

Did you use syntax like

	clear Mod1
	clear Mod2
	keycode 66 = Meta_L
	add Mod1 = Meta_L

How and when do you try to tell X11 the new key meanings?

$ sumascii BILL GATES

  66+ 73+ 76+ 76+ 71+ 65+ 84+ 69+ 83 = 663

  and add 3 because he's Bill Gates the third.

This is the contents of my .xmodmaprc

remove mod2 = Alt_L
remove mod1 = Alt_L
remove mod2 = Mode_switch
remove mod1 = Mode_switch
remove mod1 = Multi_key
add mod2 = Mode_switch
add mod2 = Alt_L

After logging in I run xmodmap .xmodmaprc followed by xmodmap -pm which prints out:

xmodmap:  up to 2 keys per modifier, (keycodes in parentheses):

shift       Shift_L (0xe8),  Shift_R (0xec)
lock        Caps_Lock (0x40)
control     Control_L (0xe7)
mod1
mod2        Mode_switch (0xed),  Alt_L (0xe9)
mod3        Num_Lock (0x5a)
mod4        Meta_L (0xea),  Meta_R (0xee)
mod5

Then I start emacs and is unable to use either alt or altgr to compose 
character such as { on my swedish layout. Howerver in all other apps (like 
thunderbird where I just wrote it), including Xemacs it works fine. I was 
hoping there was away to do this internally in emacs.

I don't know xev, neither can I find it on my system.

Hope this is helps you help me

This is a very bad layout: Mode_switch and Alt modifier are probably 
related to each other as football and soccer. The one changes the 
operating mode of the keyboard, the latter just selects another keysym 
from the few which are assigned to a key (keycode  34 = 7 slash bar 
backslash).

I am sure Solaris 9 has xev, in former versions it was a bit hidden.

I think you should just swap the two keys Mode_switch and Alt_L (which 
should be renamed to Alt_R accordingly). You'll need the Mode_switch to 
access the layers with diacritics. The syntax would be like:

	keycode <number one> = Mode_switch
	keycode <number two> = Alt_R

You can retrieve the keycodes without xev if xmodmap supports -pke.

Please use clear to clean modifier settings. Clear and remove are 
distinct. Clear only removes a setting from a modifier, so that it's 
now empty, undefined, free for a new setting. Remove deletes a keysym 
from the map, it's lost and cannot be re-used as a modifier. Consult 
'man xmodmap' and spend some time with it!

Just out of curiosity, does anyone know what it takes to run this
automatically on login (on Solaris if that makes a difference).  It
gets kinda tiresome to type this every time I work at the console
where the keyboard layout doesn't suit me.

If you put that invocation into .openwin-init, .xsession, or whatever 
launches the X11 environment for you, it takes some milli seconds ...

Thanks, now I use the following .xmodmaprc and it works in emacs too.

clear mod2
clear mod1
keycode 237 = Mode_switch
keycode 233 = Mode_switch
add mod2 = Mode_switch
add mod1 = Multi_key

Re: Mapping alt to altgr

I put the following in my .xinitrc file

xmodmap .xmodmaprc

but it depends on what windowmanager etc you are using if it is run or not. 
Othwerwise there is a similar file such as .cderc (IIRC) for the CDE window 
manager, consult your window mangagers help or ask google.
