Possibly this: When a key is pressed, a key-code can be read from your program to detect the event and the associated key. Pressing 2 keys (as described in this case it seems) has it's own key-code, instead of a combination of the 2 key-codes for each individual key. For example CTRL could have key-code ==> 0008 And 'TAB' could have a key-code ==> 0002 But pressing CTRL+tab ==> 1010
