Reverse the Table autocompletion ?

[melMass]

Hello,

I'm currently building some documentation and discovered this AMAZING addition.
It's really intuitive, I've personally rebind the Command+Shit+T to Control+T as I don't use transpose.

I'm dealing with LOTS of tables so magic table is just perfect for that except for one thing, is it possible to reverse the autocompletion ? Technically I think it should be possible since autocompletion on table edit is working pretty well. Any Clue ?
I'm dealing with long strings so the editing is a bit hard

Thanks a lot mgaitan
