Mapping AltGr key to act as WIN key

Hi,
I use ubuntu on a thinkpad X31 with PC102 keyboard with no WIN key. I wish to map the Rt Alt (AltGr) key to act as WIN key (for compiz shortcuts)
How can I do this?
Thanks in advance,
Krishna

First you need to find out what the keycode is for the key you want to map. Bring up a terminal and type in the following, followed by the Enter key:

Code:

xev

Then press on the Right Alt key. In the terminal you will see something like this:

Code:

KeyRelease event, serial 31, synthetic NO, window 0x3800001,

    root 0x5e, subw 0x0, time 9174459, (-616,-31), root:(482,587),

    state 0x8, keycode 113 (keysym 0xffeb, Alt_R), same_screen YES,

The part you need to know is the keycode which here is 113.

The other thing you need to know is Super_L is the name of the left windows key.

Close xev and in the terminal go to your home directory and make a file called .Xmodmap. I doubt that you already have one. Use whatever text editor you know, but don't use a word processor. I show using nano here.:

Code:

cd

nano .Xmodmap

In the file type. Substitute the keycode that you found in xev for the 113:

Code:

keycode 113 = Super_L

After this, log off and back on to incorporate the new addition to your keymapping. After this when you run xev and press the key, you should see Super_L instead of Alt_R.

Strangely enought the .Xmodmap didn't work with wmii (where I like to use Mod4 as the modifier)
Based on your solution I created a .xsessionrc in my home folder with this line:
xmodmap -e "keycode 108 = Super_L"
This seems to work like a charm.
Thanks for your help

under ubuntu 8.10, system->Preferences->Keyboard->Layouts(tab)->Other Options->Alt/Win key behavior->select "Left Alt is swapped with left win key"
