DirectFB distinguishes the following states: keycode - this is just a number corresponding to a physical key. My keyboard outputs numbers from 0 to 127. identifier - this is an ID corresponding to the physical letter written on the key. So with this you distinguish QWERTY from AZERTY, e.g. symbol - this is the key shown on the screen. It comes in 4 flavours: no modifiers pressed, SHIFT, AltGR, and SHIFT+AltGR. in the end, you can specify 7 values for each key: code, id, 4 symbols and lock state. lock state modifies the modifiers :) e.g. if you have CapsLock on and press SHIFT on the letter "A" you want "a" and not "A" to show, for this you enable the CapsLock lock state on the keycode corresponding to the A.
