Completion, cell-forward and the Tab key

[Dov Feldstern]

Hi!

How is the tab key bound to the completion function? I don't see it 
anywhere in the bind files...

My problem is this: in tables, Tab is already bound to cell-forward (in 
site.bind, which is hardcoded to be read --- in two places, no less: 
Lyx::init and PrefShortcuts::apply), but now with the completion code, 
Tab is not doing cell-forward anymore --- I'm guessing because it now 
does completion.

IMO, Tab should remain cell-forward --- it's quite standard, and 
Shift-Tab still does cell-backward. OTOH, Tab for completion, while 
standard in the shell, is not, I think, standard in editors (vim uses 
Ctrl-p, emacs uses Alt-\ if I remember correctly?). So I think it would 
be better if LyX would adopt a different key-binding for completion, and 
keep the Tab as cell-forward.

Thanks!
