Is it possible to have some program seperate from the WM that receives
all keystrokes starting with super (and maybe Alt to)?
Or is wmiirc+wmiiloop already a program that does exactly that
(independantly from WMII)?

I'm OK with hjkl as long as it's configurable. AFAIK one can't xmodmap
hjkl to e.g. asdf or jklæ (as that would ck lash with typing of hjkl).
Wouldn't it suffice to xmodmap ^h ^j ^k ^l to the arrow keys?
And maybe ^n and ^p to pageUp and pageDown. Then when I toggle
Ctrl-mode hjkl (or whatever keys I xmodmapped to arrows) will do what's
expected. I think this is possible both under X and in the Linux VTs.
If I knew how to do this, I could use a modular interface to Nano!
