I need to detect whether a given key is up/down - how can I do this?

I noticed that for system keys like Ctrl/Spacebar/etc a key event gets sent once when it is pressed and a second time OR'd with K_KEYUP, when it is released. However this is not the case for other basic keys (e.g. a-z, etc).

Thanks in advance,
Luke

Actually, it is case for them too. They are comming twice, once as K_A, second time as 'a'. There is then K_KEYUP|K_A (but not K_KEYUP|'a').
