Undo will undo exactly the action you did, nothing more, nothing  
less. So if you have a column selection and fire an action that  
overwrites it, run a command, and insert a snippet, pressing undo  
will bring you back to before that, and even with the column re- 
selected (something I haven't seen other editors do).

This is on the to-do -- one problem though is that a) I'm not really  
aware of all actions executed (although what the framework does w/o  
me knowing is minimal), and b) I can't fully mimic how the system  
translate menu keys. This is not just the Dvorak - Qwerty hybrid, but  
things like option-cmd 8, which on the US keyboard would fire an  
action bound to option-cmd 8, but on a “most of Europe” keymap, would  
fire an action bound to cmd [.

Althoigh I think by now, I'm pretty close to mimicking the system  
with my rather heuristic approach…
