Mnemonics/accelerators should simply be checked before widget keys. 
(Rational explained in some detail in one of my previous mails.)

GtkEntry/GtkText swallowing accelerators Alt-F is an extremely 
common problem with GTK+-1.2.

Basically, GtkEntry/GtkText should have no Alt-xx modifiers by default,
but I think checking the accelerators first is the best way to 
ensure things work properly.
