Don't use z or y keys - due to qwerty vs qwertz keyboards.

IMO they are not adjacent enough to be really quick and convenient in
use.

Let:

1. eyes focus on the monitor
2. brain do the interpretation
3. main hand point the location using mouse
4. secondary hand perform the action using keys, in a way that your
eyes are not distracted from wathing the display and your brain is not
involved in chossing the right key

Any key mapping that follows this is be good. staqd(x) isn't.

Not bad. But IMHO even more ergonomic is sxacq for right-handed people
and kmlno for left hand-handed:

Zoom-in:	s or k
Zoom-out:	x or m
Pan:		a or l
Query:		c or n

Measure:	q or o

But I wont insinst anymore if you can tell why my proposition is bad.

Good point.
