Caps-Lock-->control BUT control--> super

[Uwe Brauer]

Hello

I know I can swap Caps-Lock and Control, either directly in the control
centre or using xmodmap.

However Caps-Lock is a function I nearly never used. So it would be much
more useful for me to map that to super(or hyper).

So the idea is to 


    -  remove Caps-Lock from the key next to the a (in QWERTY) 

    -  to map control on that key.

    -  to remove control from the key next to z (in QWERTY) and map
       super or hyper to it.

Is this possible.

I tried.

keycode 0x25 =	Super_L

clear mod3 
add mod3 = Super_L Super_R

That works but xmodmap complains and I would like to know whether there
exists a clean way to do this.


thanks
