Tab is still used to cycle, but it will move to the next widget much
quicker.  I've got no problem with making other keys cycle if
people come to an agreement about which keys to use :)

Currently:
ENTER accepts the expanded alias, and goes to the next widget.
DOWN ignores the expanded alias, and goes to the next widget.
TAB cycles if it can, otherwise it goes to the next widget.

I need:
- At least one key to cycle (currently tab).
- At least one key to go to the next entrybox accepting the alias.
- At least one key to go to the next entrybox ignoring the alias.

This is a request-for-comment :)  Anybody please give opinions.
I need final keystrokes before I update the documentation.

I'm all for that.  I gotta read up a LOT on GTK, and read the actual
GTK source before I do that!  It'll be ready in 2002.  Seriously, I
would like that very much, but the alias stuff needs fixing much more
urgently than I can create BalsaAddressEntry.  However, if someone
can get me started...

Hmm, the data structures aren't horribly complex anymore.  The bigger
advantage is that I don't have to guess (and it is a guess) what
happened when the widget loses focus, and regains focus.  Its necessary
because the mouse can move the cursor.
