/*
 * Reserved range for evdev symbols: 0x10081000-0x10081FFF
 *
 * Key syms within this range must match the Linux kernel
 * input-event-codes.h file in the format:
 *     XF86XK_CamelCaseKernelName	_EVDEVK(kernel value)
 * For example, the kernel
 *   #define KEY_MACRO_RECORD_START	0x2b0
 * effectively ends up as:
 *   #define XF86XK_MacroRecordStart	0x100812b0
 *
 * For historical reasons, some keysyms within the reserved range will be
 * missing, most notably all "normal" keys that are mapped through default
 * XKB layouts (e.g. KEY_Q).
 *
 * CamelCasing is done with a human control as last authority, e.g. see VOD
 * instead of Vod for the Video on Demand key.
 *
 * The format for #defines is strict:
 *
 * #define XF86XK_FOO<tab...>_EVDEVK(0xABC)<tab><tab> |* kver KEY_FOO *|
 *
 * Where
 * - alignment by tabs
 * - the _EVDEVK macro must be used
 * - the hex code must be in uppercase hex
 * - the kernel version (kver) is in the form v5.10
 * - kver and key name are within a slash-star comment (a pipe is used in
 *   this example for technical reasons)
 * These #defines are parsed by scripts. Do not stray from the given format.
 *
 * Where the evdev keycode is mapped to a different symbol, please add a
 * comment line starting with Use: but otherwise the same format, e.g.
 *  Use: XF86XK_RotationLockToggle	_EVDEVK(0x231)		   v4.16 KEY_ROTATE_LOCK_TOGGLE
 *
