[squeak-dev] for the morphic team...is a "caps locks is on" indicator doable?

Hi there.

This should work: 

| capsLockFilter |
capsLockFilter := PluggableEventFilter on: [:keyboardEvent |
	(keyboardEvent isKeystroke
		and: [keyboardEvent keyCharacter isUppercase
		and: [keyboardEvent shiftPressed not]])
			ifTrue: [self inform: 'CAPS LOCK ON'].
self currentHand addKeyboardCaptureFilter: capsLockFilter.

Be sure to find a safe place for that capsLockFilter so that it won't be
garbage collected. :-) Maybe that "inform:" is too noisy for you. I don't
