// sc: the hardware keycode (in Windows, it's called scan code).

// MAP2: maps from ch0+ch1+sc to vk.
// MAP3: maps from ch0+ch1+ch2+sc to vk.
// MAP0 - MAP3 are all sorted, so that finding VK can be binary search.

// Reason for creating these maps is because a hard-coded mapping in
// KeyboardCodeFromXKeysym() doesn't support non-US keyboard layouts.
// e.g. in UK keyboard, the key between Quote and Enter keys has the VKEY code
// VKEY_OEM_5 instead of VKEY_3.
//
// The key symbols which are not [a-zA-Z0-9] and functional/extend keys (e.g.
// TAB, ENTER, BS, Arrow keys, modifier keys, F1-F12, media/app keys, etc.)
// should go through these maps for correct VKEY codes.
//
