MenuItem accelerator: nothing happens or NPE

Meanwhile we could workaround the problem with an event filter for 
KEY_PRESSED. I guess it is acceptable for just one shortcut (F1 for 
online help). But see below.

Unfortunately that is not the case. With

   new KeyCodeCombination(KeyCode.A, KeyCombination.CONTROL_DOWN)

the same NPE occurs. What's more, if I use

   new KeyCodeCombination(KeyCode.A, KeyCombination.META_DOWN)

there are two problems:

1. META maps to the windows key. Javadoc says it maps to the control key
on Windows.

2. The combination above is displayed as "Meta+A" on Windows. I would 
have expected "Ctrl+A", or even "Win+A" since "Meta" is not really a 
common keyname on Windows, especially for end-users...
