114 * Getting a keycode from scancode
115 *
116 * With XKB
117 * --------
118 *
119 * We have to enqueue keyboard events using standard X keycodes which correspond
120 * to AT scancode + 8; this means that we need to translate the Linux scancode
121 * provided by the kernel to an AT scancode -- this translation is not linear
122 * and requires that we use a LUT.
123 *
124 *
125 * Without XKB
126 * -----------
127 *
128 * We can use custom keycodes, which makes things simpler; we define our custom
129 * keycodes as Linux scancodes + KD_KEY_OFFSET
130*/

133 This LUT translates AT scancodes into Linux ones -- the keymap we create
