Hi Jan,

Your patch breaks overriding accelerators which as I said before is a
critical accessibility feature.

The current code works for me but I realize it's using an unsupported
interface.  I'll spend some time today trying to find a work around.
But we definitely cannot assume that the accelerators are using any
specific modifiers.
