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

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 
.IR 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might be immediately superseded by automatic changes to the indicator state if 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.
