Accelerators - odd behavior

[Tomas Mikula]

> That doesn't explain why this isn't happening for PLUS.

KeyCodeCombination(KeyCode.PLUS, KeyCombination.CONTROL_DOWN)

is never matched. It might even be impossible to get a KEY_PRESSED
event with key code PLUS with English keyboard layout. When I switch
keyboard layout to Slovak, which has the '+' sign accessible without
Shift, I do get the runnable fired twice.

Best,
Tomas
