 The trouble is that this is really the only other standard key for doing
this. We discussed it already with Vaclav and neither of us could really
come with any good alternative. So if we don't use Space, what do we use?
Perhaps nothing and just start editing in place whenever any character-
generating key (i.e. not something like a cursor arrow or function key or
...) is pressed, like in a spreadsheet or wxGrid? Or would this result in
too much accidental editing for LMI users?

 This is definitely a bug, Alt-Spacebar shouldn't be intercepted by this
code, we need to fix this in any case.

 I agree that F2 is not especially convenient (nor that easily
discoverable) but I really don't see any key other than Space that could
be reasonably used for this. What is the problem with using Space BTW?
