action in which to set ctrls0-ctrls3

Actions associated with the XkbCtrlsAction structure change the state of the
boolean controls.
The

field can have any one of the values shown in Table 1.

Table 1 Controls Action Types
_
Type Effect
_
XkbSA_SetControls T{
A key press enables any boolean controls specified in the ctrls fields that were
not already enabled at
the time of the key press.
A key release disables any controls enabled by the key press.
This action can cause XkbControlsNotify events.
T}
XkbSA_LockControls T{
If the XkbSA_LockNoLock bit is not set in the flags field, a key press enables
any controls specified in
the ctrls fields that were not already enabled at the time of the key press.
.br
If the XkbSA_LockNoUnlock bit is not set in the flags field, a key release
disables any controls
specified in the ctrls fields that were not already disabled at the time of the
key press.
.br
This action can cause XkbControlsNotify events.
T}
.TE
The
.I flags
field is composed of the bitwise inclusive OR of the masks shown in Table 2.

Table 2 Control Action Flags
_
Flag Meaning
_
XkbSA_LockNoLock T{
If set, and the action type is XkbSA_LockControls, the server only disables
controls.
T}
XkbSA_LockNoUnlock T{
If set, and the action type is XkbSA_LockControls, the server only enables
controls.
T}
.TE
The XkbSA_SetControls action implements a key that enables a boolean control
when pressed and disables it
when released. The XkbSA_LockControls action is used to implement a key that
toggles the state of a
boolean control each time it is pressed and released. The XkbSA_LockNoLock and
XkbSA_LockNoUnlock flags
allow modifying the toggling behavior to only unlock or only lock the boolean
control.
The
.I ctrls0, ctrls1, ctrls2,
and
.I ctrls3
fields represent the boolean controls in the
.I enabled_ctrls
field of the controls structure. Xkb macros, to convert between the two formats.
.I XkbSAActionSetCtrls
sets the
.I ctrls0
through
.I ctrls3
fields of
.I act
from
.I ctrls.
