Navigation with arrow keys

[egbert]

Hello group,
Within a multiline TextCtrl I can go to different lines
with the up and down arrows. 
However when I am on the first or last line, I want to go
with these same keys to the prior or next widget.

This must be quite natural to naive users, as they don't seem
to make the subtle distinction between widgets and lines.

I suppose that in order to implement this, I have to detect
if I am on the first/last line of the TextCtrl, or somewhere
in between. How do I do that ? I saw no relevant methods.
