+1 to Sig's comments. Another problem with looking at the current state vs. state from an event is that the current state is just that, and often differs (covertly and frustratingly) from the user's intentions. Such problems often arise with mouse cursor positions.

Hi,
How can I check whether a certain key is pressed (for example, a modifier like Shift)?
Depends on context. In Morphic, just take an event (mouse event or keyboard event) and send #shiftPressed, or #controlKeyPressed, or whatever. Another way is to ask the Sensor for same things, but i wouldn't do that, because to my opinion this is the wrong way, because Sensor is low-level object, which should be hidden from the eyes of developer, and normally, if you need to use it, it means that you doing something wrong :)
Cheers, Doru
