 * The key symbol space is divided into "classes" where
 * the high 8 bits determine the symbol class, and the
 * low 8 bits are interpreted in a way specific to each
 * class.  The simplest class is ASCII, which is defined
 * as class zero in order to simplify table definition.
 *
 * For convenience in the driver, all keysyms that
 * deserve autorepeat are below 0x8000.  The driver
