Ideally I would like to have them user configurable, but

the left hand is
I for zoom In
T for zoom ouT
A for pAn
Q for Query
D for Distance (Measure)
X for pointer

That is in my opinion a perfectly functional one hand configuration
unless you use a non Qwerty keyboard.

For the right it is less functional because of ? for Query, but rather
obvious. Possibly U would work better or allow ? or U to work.

Personally, I would prefer to integrate zoom and pan into a single tool
and pointer and query together too, but for new users, this kind of
functionality is often missed. Thus the conflict; we want our own GUI
(rather and QGIS) in part because GRASS is not for GIS newbies, but at
the same time we want to keep the learning curve as gentle as possible.

Perhaps multi-functionality could be built into the zoom in and pointer
tools (using Ctrl and Shift) and reduce the keystrokes to switching
between zoom and pointer only.
