   * Test a sequence of keysyms, resulting from a sequence of key presses,

   * - Each test runs with a clean state.
   * - Each line in the test is made up of:
   *   + A keycode, given as a KEY_* from linux/input.h.
   *   + A direction - DOWN for press, UP for release, BOTH for
   *     immediate press + release, REPEAT to just get the syms.
   *   + A sequence of keysyms that should result from this keypress.
   *
   * The vararg format is:
   * <KEY_*>  <DOWN | UP | BOTH>  <XKB_KEY_* (zero or more)>  <NEXT | FINISH>
