BackKey in browser widget

[J. Landman Gay]

I mean the hardware backKey that can be trapped with a backKey handler 
normally, but the browser widget takes it over. I don't mind if the user 
wants to backtrack through the links they've visited, but when they get 
to their entry point bad things happen; I can't remember exactly what 
went wrong (it was a couple of days ago,) but either it was a crash or a 
badly drawn card. So my idea was to only use the backKey to navigate 
cards and disallow backtracking in the browser. But I can't trap for it 
there.
