DESCRIPTION

       Auto-repeat is the generation of multiple key events by a keyboard when the user presses a
       key and holds it down. Keyboard hardware and  device-dependent  X  server  software  often
       implement   auto-repeat  by  generating  multiple  KeyPress  events  with  no  intervening
       KeyRelease event. The standard behavior of the X server is to generate a KeyRelease  event
       for  every KeyPress event. If the keyboard hardware and device-dependent software of the X
       server  implement  auto-repeat  by  generating  multiple  KeyPress  events,  the   device-
       independent  part  of  the  X server by default synthetically generates a KeyRelease event
       after each KeyPress event.  This provides predictable behavior for X clients, but does not
       allow those clients to detect the fact that a key is auto-repeating.

       Xkb allows clients to request detectable auto-repeat.  If a client requests and the server
       supports DetectableAutoRepeat, Xkb generates  KeyRelease  events  only  when  the  key  is
       physically  released.  If DetectableAutoRepeat is not supported or has not been requested,
       the server synthesizes a KeyRelease event for each repeating KeyPress event it generates.

       DetectableAutoRepeat, unlike other  controls,  is  not  contained  in  the  XkbControlsRec
       structure,  nor  can  it  be enabled or disabled via the EnabledControls control. Instead,
       query    and    set    DetectableAutoRepeat    using    XkbGetDetectableAutoRepeat     and
       XkbSetDetectableAutoRepeat.

       DetectableAutoRepeat  is  a  condition that applies to all keyboard devices for a client's
       connection to a given X server; it cannot be selectively set for some devices and not  for
       others.  For this reason, none of the Xkb library functions involving DetectableAutoRepeat
       involve a device specifier.

       This request affects all keyboard activity for the requesting client only;  other  clients
       still  see  the  expected  nondetectable  auto-repeat behavior, unless they have requested
       otherwise.

       XkbSetDetectableAutoRepeat sends a request to the server to  set  DetectableAutoRepeat  on
       for  the  current  client  if  detectable is True, and off if detectable is False; it then
       waits for a reply. If supported_rtrn is  not  NULL,  XkbSetDetectableAutoRepeat  backfills
       supported_rtrn with True if the server supports DetectableAutoRepeat, and False if it does
       not.  XkbSetDetectableAutoRepeat returns the current state of DetectableAutoRepeat for the
       requesting client: True if DetectableAutoRepeat is set, and False otherwise.

RETURN VALUES

       True           The     XkbSetDetectableAutoRepeat     function     returns     True     if
                      DetectableAutoRepeat is set.

       False          The    XkbSetDetectableAutoRepeat     function     returns     False     if
                      DetectableAutoRepeat is not set.
