38 In environments where computers are shared, features such as SlowKeys
39 present a problem: if SlowKeys is on, the keyboard can appear to be un‐
40 responsive because keys are not accepted until they are held for a cer‐
41 tain period of time. To help solve this problem, Xkb provides an Ac‐
42 cessXTimeout control to automatically change the enabled/disabled state
43 of any boolean controls and to change the value of the AccessXKeys and
44 AccessXFeedback control attributes if the keyboard is idle for a speci‐
45 fied period of time.
46 When a timeout as specified by AccessXTimeout occurs and a control is
48 consequently modified, Xkb generates an XkbControlsNotify event.
49 XkbGetAccessXTimeout sends a request to the X server to obtain the cur‐
51 rent values for the AccessXTimeout attributes, waits for a reply, and
52 backfills the values into the appropriate arguments. The parameters op‐
53 tions_mask_rtrn and options_values_rtrn are backfilled with the options
54 to modify and the values for ax_options, which is a field in the Xkb‐
55 ControlsRec structure. XkbGetAccessXTimeout returns True if success‐
56 ful; if a compatible version of the Xkb extension is not available in
57 the server, XkbGetAccessXTimeout returns False.

60 True The XkbGetAccessXTimeout returns True when it success‐
61 fully sends a request to the X server to obtain the cur‐
62 rent values for the AccessXTimeout attributes, waits for
63 a reply, and backfills the values into the appropriate
64 arguments.
65 False The XkbGetAccessXTimeout function returns False if a
67 compatible version of the Xkb extension is not available
68 in the server.
