[Gzz] We need four wheel-turner keys

[Benja Fallenstein]

Hi Tuukka--

I just tried out different key assignments for the wheel views, and 
having four wheel-turner keys as you proposed-- one for "rotate up on 
right side," one for "rotate down on right side," and corresponding for 
left-- was the only one that really worked smoothly. I'm impressed-- I 
didn't consider this to be a good contender when you first brought this up.

I've used j/l for left/right and u/o/n/. for the wheel-turners. n seems 
more appropriate than m somehow, my finger glides on that (n) automatically.

To avoid mode errors, maybe these should work in the normal views, too? 
Of course, then "Rotate up on left side" and  "Rotate up on right side" 
would mean the same thing, just as in the wheel views "Rotate up on left 
side" and "Rotate down on right side" are same.

I'm not sure whether up/down (i/,) should also work in the non-wheel 
views (seems to open up the possibility for mode errors?). Also not sure 
how to map this to the cursor keys.

*sigh*

Opinions?
