The control key results in modifiers having Qt::MetaModifier, and then
the correct character is found in charactersIgnoringModifiers. The
rest of the time, [nsevent characters] seems to be correct. If we
use charactersIgnoringModifiers too much of the time, then the keycode
will be wrong in some cases even though typing is still possible.
