Comment 2 for bug 389929

The best example is for choose the keyboard layout.
There is a pop-up menu with like 40 different countries.
I can't access to france just by tape "france", and I can't neither go the countries with a name in "F..." by pressing "F".
There is the same issue for choose the language of the system.

I think gtk should support the keyboard access in pop-up menus, at least in these which are sorted alphabetically.
