DESCRIPTION

19       Actions associated with the XkbCtrlsAction structure change  the  state
20       of the boolean controls.
21
22       The type field can have any one of the values shown in Table 1.

28       ──────────────────────────────────────────────────────────────
29       XkbSA_SetControls    A key press enables any boolean controls
30                            specified in the ctrls fields that  were
31                            not  already  enabled at the time of the
32                            key press.  A key release  disables  any
33                            controls enabled by the key press.  This
34                            action   can   cause   XkbControlsNotify
35                            events.
36       XkbSA_LockControls   If  the  XkbSA_LockNoLock bit is not set
37                            in the flags field, a key press  enables
38                            any  controls  specified  in  the  ctrls
39                            fields that were not already enabled  at
40                            the time of the key press.
41                            If the XkbSA_LockNoUnlock bit is not set
42                            in the flags field, a key  release  dis‐
43                            ables  any  controls  specified  in  the
44                            ctrls fields that were not already  dis‐
45                            abled at the time of the key press.
46                            This  action can cause XkbControlsNotify
47                            events.
48
49       The flags field is composed of the bitwise inclusive OR  of  the  masks
50       shown in Table 2.

57       XkbSA_LockNoLock     If   set,   and   the   action  type  is
58                            XkbSA_LockControls, the server only dis‐
59                            ables controls.
60       XkbSA_LockNoUnlock   If   set,   and   the   action  type  is
61                            XkbSA_LockControls, the server only  en‐
62                            ables controls.
63
64       The  XkbSA_SetControls  action  implements a key that enables a boolean
65       control when pressed and disables it when released. The  XkbSA_LockCon‐
66       trols  action  is  used  to implement a key that toggles the state of a
67       boolean control each time it is pressed and  released.  The  XkbSA_Loc‐
68       kNoLock  and  XkbSA_LockNoUnlock flags allow modifying the toggling be‐
69       havior to only unlock or only lock the boolean control.
70
71       The ctrls0, ctrls1, ctrls2, and ctrls3  fields  represent  the  boolean
72       controls  in  the  enabled_ctrls  field  of the controls structure. Xkb
73       macros, to convert between the two formats.
74
75       XkbSAActionSetCtrls sets the ctrls0 through ctrls3 fields of  act  from
76       ctrls.
