/* So here's how linux works with key mapping:
 *
 * First, there's a global key symbol enum (xcb_keysym_t) which has unique
 * values for all possible symbols keys can have (e.g., '1' and '!' are
 * different values).
 *
 * Then there's a key code (xcb_keycode_t), which is basically an index to the
 * actual key itself on the keyboard (e.g., '1' and '!' will share the same
 * value).
 *
 * xcb_keysym_t values should be given to libobs, and libobs will translate it
 * to an obs_key_t, and although xcb_keysym_t can differ ('!' vs '1'), it will
 * get the obs_key_t value that represents the actual key pressed; in other
 * words it will be based on the key code rather than the key symbol.  The same
 * applies to checking key press states.
