+.SH DESCRIPTION
+.LP
+The server can generate XkbAccessXNotify events for some of the global keyboard
+controls.
+The detail field describes what AccessX event just occurred and can be any of
+the values in
+Table 1.

+XkbAXN_SKPress T{
+A key was pressed when SlowKeys was enabled.
+T}
+XkbAXN_SKAccept T{
+A key was accepted (held longer than the SlowKeys delay).

+An accepted SlowKeys key was released.

+
+The
+.I keycode
+field reports the keycode of the key for which the event occurred. If the action
+is related to
+.I SlowKeys,
+the
+.I slowKeysDelay
+field contains the current SlowKeys acceptance delay. If the action is related
+to BounceKeys,
+the
+.I debounceDelay
+field contains the current BounceKeys debounce delay.
+
+Selecting for AccessX Events
+
+To receive XkbAccessXNotify events under all possible conditions, use
+.I XkbSelectEvents
+and pass XkbAccesXNotifyMask in both
+.I bits_to_change
+and
+.I values_for_bits.
+
+To receive XkbStateNotify events only under certain conditions, use
+.I XkbSelectEventDetails
+using XkbAccessXNotify as the
+.I event_type
+and specifying the desired state changes in
+.I bits_to_change
+and
+.I values_for_bits
+using mask bits from Table 2.

+.TE
+
+Some users may accidentally "bounce" on a key when they release it. They press
+it once, then accidentally press it again after they release it. The BounceKeys
+control temporarily disables a key after it has been pressed, effectively
+"debouncing" the keyboard. The period of time the key is disabled after it is
+released is known as the
+.I BounceKeys delay.
+BounceKeys is a boolean control.
+
+When the BounceKeys control is active, the server reports acceptance or
+rejection of any key to interested clients by sending an appropriate
+AccessXNotify event.
+
+.I XkbSetBounceKeysDelay
+sends a request to configure the BounceKeys control to the server. It does not
+wait for a reply and normally returns True. Specifying a value of zero for the
+delay parameter causes
+.I XkbSetBounceKeysDelay
+to generate a BadValue protocol error. If a compatible version of the Xkb
+extension is not available in the server,
+.I XkbSetBounceKeysDelay
+returns False.
+.SH "RETURN VALUES"
+.TP 15
+True
+The
+.I XkbSetBounceKeysDelay
+function returns True when it sends a request to configure the BounceKeys
+control to the server.
+.TP 15
+False
+The
+.I XkbSetBounceKeysDelay
+function returns False if a compatible version of the Xkb extension is not
+available in the server.
+.SH STRUCTURES
+.LP
+The structure for the XkbAccessXNotify event type is as follows:
+
+.nf
+typedef struct {
+ int type; /\(** Xkb extension base event code */
+ unsigned long serial; /\(** X server serial number for event */
+ Bool send_event; /\(** True => synthetically generated */
+ Display * display; /\(** server connection where event generated */
+ Time time; /\(** server time when event generated */
+ int xkb_type; /\(** XkbAccessXNotify */
+ int device; /\(** Xkb device ID, will not be XkbUseCoreKbd
+*/
+ int detail; /\(** XkbAXN_* */
+ KeyCode keycode; /\(** key of event */
+ int slowKeysDelay; /\(** current SlowKeys delay */
+ int debounceDelay; /\(** current debounce delay */
+} XkbAccessXNotifyEvent;
