We've been able to think of only two reasonable options:
toggle the value (current behavior), or do nothing.

Is there some relatively easy way we could experiment
with both behaviors, e.g., by applying some small
patch and rebuilding wx? I ask because it's often
easier to evaluate alternative behaviors by playing
with both. One idea would be a throwaway patch that
leaves the F2 behavior as is, and maps F3 to the
previous wxGrid behavior you describe above.

BTW, that sounds weird to me, for a different reason:
other controls (comboboxes, for instance) that ask
the user to make a choice do not end editing as soon
as a choice is made.
But it's interesting that you mention pressing Space
to begin editing. We discussed this already:
and concluded that for a text-edit grid cell, Space
should do what it does now in wxGrid (that is, delete
contents and enter edit mode) because that's what it
would do in a spreadsheet program. In light of that,
it seems natural and obvious that pressing Space
should toggle the state of a textbox grid cell.
Yet this leads me down a new line of inquiry...
- Should Space be a synonym for F2? If so, then Space
naturally toggles a checkbox, and it would follow that
F2 should do the same. But the initial premise fails:
we already decided, correctly, that normal spreadsheet
behavior is expected, and therefore Space and F2 must
do different things in a text-edit cell.
- Then why do we even ask what Space should do?
Does the question occur to us only because Space is
a way to enter "edit mode" in wxDvc? Or is it merely
because Space exists, and pressing it must map to
- Might end users think of Space as the census
manager's begin-editing key, because of previous
experience with the wxDVC implementation? Or would
they have used F2 for that purpose, as I did because
of my experience with disco-era spreadsheet programs?
Or, these being modern times, would they avoid the
keyboard and just use the mouse or tap the screen, in
which case we don't need to worry about what F2 does?
(I suppose we'll have to ask them.)

Comparing the wxDVC and wxGrid census managers,
when a checkbox cell is selected: Space does the
same thing in both, but F2 behaves differently,
which might surprise users accustomed to the
old behavior. Again, we'll want to consult them.
