Clear yes, but also about 3 times smaller than on your desktop screen...

Which gives rise to the question of how to best arrange them...

Add another button that allows to tap shortcuts (for example like it is done 
in some of the vnc clients). In general, I find I'm using LESS keys for 
terminal work than for text entry. YMMV.

I meant for the second level, where they are essentially already in a 
hexagonal shape...

If you use drag vectors instead of actual taps on the buttons, you might get 
away with very short drags, really.

Do you really need all those keys? I generally don't. Then again, I don't plan 
on doing non emergency work in terminals either... And on a notebook you 
usually don't have all of them for direct access, either.
