TAB as alternative to ENTER for tag completion

[gpm2a]

oXygen's Code Insight feature requires that you use the ENTER key to auto-complete the currently highlighted tag. But using TAB for this purpose is also very common -- for example in web browsers -- I would say more common than ENTER (on Windows, at least). It would be nice if TAB behaved just like ENTER does now -- complete the tag rather than inserting an actual TAB character.
