Most of my writing, editing, and programming is done using Emacs as a multipurpose text editor. I'm attracted to the idea of the Twiddler letting me type while walking or lying in bed. But before going through the process of learning the Twiddler's ways, programming it to my satisfaction, and training myself to use it, I would like to know what other Emacs lovers have found out about it. Do you have a recommended Twiddle keyboard configuration for Emacs?
Have you found unsurmountable difficulties---Emacs things that you couldn't manage to do? Or things you can do but are very awkward?
In sum, ito what extent is the Twiddler "Emacs compatible"?
