That does sound very useful.

Just for reference, after posting I figured out a solution to my 
current problem.  I can let, say, the pressing of a numeric key 
start the editing of a treeview cell.  But then how to get this 
first number into the editable cell?  Aha, synthesize an artificial 
key_press event using the keyval from the real key_press that we 
captured.  Works nicely.
