This section discusses the effects of explicitly changing indicators depending
upon different settings in the indicator map. See Tables 1 and Table 2 for
information on the effects of the indicator map fields when explicit changes are
made.

The groups field is treated as a group mask. If the indicator is explicitly
extinguished, keyboard group

is zero, the keyboard
group latch is set to the index of the highest legal keyboard group.

If XkbIM_LEDDrivesKB is set and XkbIM_NoExplicit is not, and if you call a
function that updates the server's image of the indicator map (such as
.I XkbSetIndicatorMap
or
.I XkbSetNamedIndicator),
Xkb changes the keyboard state and controls to reflect the other fields of the
indicator map. If you attempt to explicitly change the value of an indicator for
which XkbIM_LEDDrivesKB is absent or for which XkbIM_NoExplicit is present,
keyboard state or controls are unaffected.
If neither XkbIM_NoAutomatic nor XkbIM_NoExplicit is set in an indicator map,
Xkb honors any request to change the state of the indicator, but the new state
might be immediately superseded by automatic changes to the indicator state if
the keyboard state or controls change.
The effects of changing an indicator that drives the keyboard are cumulative; it
is possible for a single change to affect keyboard group, modifiers, and
controls simultaneously.
If you change an indicator for which both the XkbIM_LEDDrivesKB and
XkbIM_NoAutomatic flags are specified, Xkb applies the keyboard changes
specified in the other indicator map fields and changes the indicator to reflect
the state that was explicitly requested. The indicator remains in the new state
until it is explicitly changed again.
If the XkbIM_NoAutomatic flag is not set and XkbIM_LEDDrivesKB is set, Xkb
applies the changes specified in the other indicator map fields and sets the
state of the indicator to the values specified by the indicator map. Note that
it is possible in this case for the indicator to end up in a different state
than the one that was explicitly requested. For example, Xkb does not extinguish
an indicator with
.I which_mods
of XkbIM_UseBase and
.I mods
of Shift if, at the time Xkb processes the request to extinguish the indicator,
one of the Shift keys is physically depressed.
If you explicitly light an indicator for which XkbIM_LEDDrivesKB is set, Xkb
enables all of the boolean controls specified in the
.I ctrls
field of its indicator map. Explicitly extinguishing such an indicator causes
Xkb to disable all of the boolean controls specified in
.I ctrls.
For each bit set in the
.I which
parameter,
.I XkbSetIndicatorMap
sends the corresponding indicator map from the
.I desc
parameter to the server.
