thanks ramones! I had no idea!
that combination is indeed one that doesn't seem supported on my keyboard.
so this means that it would be a limitation in my game.. some people may have a keyboard that doesn't support those 3 keystrokes... interesting...
I wonder if it's just older keyboards, because the keyboard I am using is from 2007, just because like I the way it types.. still someone playing my game would probably assume it's a game bug.. like I did! I wonder if that's why a lot of people use keyboard-mouse combos. My game is more suited for keyboard only.. so I have no idea what I will do to work around this..
