  32  * the high 8 bits determine the symbol class, and the

  34  * class.  The simplest class is ASCII, which is defined
  35  * as class zero in order to simplify table definition.

  38  * deserve autorepeat are below 0x8000.  The driver
  39  * uses the following macro to determine if a keysym
  40  * should NOT get autorepeat.
