fix Vi-like navigation shortcuts
Review Request #102255 - Created Aug. 8, 2011 and submitted
this feature got reverted by adjam with revision a47bb905 because there was no check if a widget stole the focus before (input or textarea). this sometimes corrupted your input. (i could reproduce it here on reviewboard) this patch fixes that feature by adding a check on the name of the active element's tag.
compiles and works
I was already not a big fan of this change the first time. Now even though the implementation is better, I still think this is gonna be a pain, e.g. for people wanting to use the shortcuts in GMail or friends. (I actually heard some complaints after the first implementation made it in...) If we really want this, I think it *has* to be an opt-in thing.
