Hi;
How can I find other keys codes?
tnx;

There is a table of ASCII codes and Windows virtual keycodes. I don't know how exactly it works, because these codes don't seem to match with ASCII or virtual key codes.

#define KEY_LEFT_CTRL   0x01
#define KEY_LEFT_SHIFT  0x02
#define KEY_RIGHT_CTRL  0x10
#define KEY_RIGHT_SHIFT 0x20
