Using emacs on a tablet computer

[joakim]

Sometimes I dont get anywhere to sit on the commuter train
and I use my laptop in tablet mode to amuse myself.

Today I tried to read things in Gnus using only the pen interface.
It didnt work out too well, basically because of lacking menu options.
Most I can fix myself of course, but what about keyboard-quit?

keyboard-quit is quite essential for emacs usage, and there doesnt seem
to be a way to map it to a  menu or toolbar button that works when you
need it.

I'm happily proven wrong of course.
