31 // These are the generated VKEY code maps for all possible Latin keyboard
32 // layouts in Windows. And the maps are only for special letter keys excluding
33 // [a-z] & [0-9].
34 //
35 // ch0: the keysym without modifier states.
36 // ch1: the keysym with shift state.
37 // ch2: the keysym with altgr state.
38 // sc: the hardware keycode (in Windows, it's called scan code).
39 // vk: the VKEY code.
40 //
41 // MAP0: maps from ch0 to vk.
42 // MAP1: maps from ch0+sc to vk.
43 // MAP2: maps from ch0+ch1+sc to vk.
44 // MAP3: maps from ch0+ch1+ch2+sc to vk.
45 // MAP0 - MAP3 are all sorted, so that finding VK can be binary search.
46 //
47 // Reason for creating these maps is because a hard-coded mapping in
48 // KeyboardCodeFromXKeysym() doesn't support non-US keyboard layouts.
49 // e.g. in UK keyboard, the key between Quote and Enter keys has the VKEY code
50 // VKEY_OEM_5 instead of VKEY_3.
51 //
52 // The key symbols which are not [a-zA-Z0-9] and functional/extend keys (e.g.
53 // TAB, ENTER, BS, Arrow keys, modifier keys, F1-F12, media/app keys, etc.)
54 // should go through these maps for correct VKEY codes.
55 //
