  Message : API to query modifier set required to type a keysym The new API is useful to implement features like auto-type and desktop automation. Since the inputs for these features is usually specified in terms of the symbols that need to be typed, the implementation needs to be able to invert the keycode->keysym transformation and produce a sequence of keycodes that can be used to type the requested character(s).
