Where I was confused is that checking if the key is pressed already

appear to differentiate between a 'real' key down and a repeat. For

:
keyDown: anEvent

ifFalse: [keys add: anEvent keyValue. "
Transcript show: 'key down ' , anEvent asString; cr.

always takes the 'key down' branch, even for key held down.
Was this what you meant?
Yes. The code above works as expected on Mac OS X, printing
"skipped..." for auto-repeats.
On the other hand, looping over this in a thread:
keyStrokes
keys
do: [:key | key
ifNotNil: [(oldKeys includes: key)
ifFalse: [Transcript show: 'key
added ' , key asString;
cr]]].
oldKeys do: [:key | key
ifNotNil: [(keys includes: key)
ifFalse: [Transcript show: 'key
removed ' , key asString;
cr]]].
oldKeys := keys copy.
has the desired effect of only showing real key moves.
Is this over complicating things?
It indeed sounds overly complicated, unless your platform forces you
to resort to such things. Are you on Linux by chance?
