.SH DESCRIPTION
.LP
The EnabledControls control is a bit mask where each bit that is turned on means the
corresponding control is enabled, and when turned off, disabled. It corresponds to the
.I enabled_ctrls
field of an XkbControlsRec structure (see STRUCTURES). The bits describing which controls are
turned on or off are defined in Table 1.
Table 1 shows the actual values for the individual mask bits used to select controls for
modification and to enable and disable the control. Note that the same mask bit is used to
specify general modifications to the parameters used to configure the control (which), and to
enable and disable the control (enabled_ctrls). The anomalies in the table (no "ok" in column)
are for controls that have no configurable attributes; and for controls that are not boolean
controls and therefore cannot be enabled or disabled.

.TE
The
.I mask
parameter specifies the boolean controls to be enabled or disabled, and the
.I values
mask specifies the new state for those controls. Valid values for both of these
masks are composed of a bitwise inclusive OR of bits taken from the set of mask
bits in Table 1, using only those masks with "ok" in the
.I enabled_ctrls
column.
If the X server does not support a compatible version of Xkb or the Xkb
extension has not been properly initialized,
.I XkbChangeEnabledControls
returns False; otherwise, it sends the request to the X server and returns True.
Note that the EnabledControls control only enables and disables controls; it
does not configure them. Some controls, such as the AudibleBell control, have no
configuration attributes and are therefore manipulated solely by enabling and
disabling them. Others, however, have additional attributes to configure their
behavior. For example, the RepeatControl control uses
.I repeat_delay
and
.I repeat_interval
fields to describe the timing behavior of keys that repeat. The RepeatControl
behavior is turned on or off depending on the value of the XkbRepeatKeysMask
bit, but you must use other means, as described in this chapter, to configure
its behavior in detail.
.SH "RETURN VALUES"
.TP 15
True
The X server supports a compatible version of Xkb.
.TP 15
False
The X server does not support a compatible version of Xkb or the Xkb extension has not been properly initialized.
