An X server can impose restrictions on how modifiers can be changed,
|
|
Packit |
5bd3a9 |
for example,
|
|
Packit |
5bd3a9 |
if certain keys do not generate up transitions in hardware,
|
|
Packit |
5bd3a9 |
if auto-repeat cannot be disabled on certain keys,
|
|
Packit |
5bd3a9 |
or if multiple modifier keys are not supported.
|
|
Packit |
5bd3a9 |
If some such restriction is violated,
|
|
Packit |
5bd3a9 |
the status reply is
|
|
Packit |
5bd3a9 |
.ZN MappingFailed ,
|
|
Packit |
5bd3a9 |
and none of the modifiers are changed.
|
|
Packit |
5bd3a9 |

|
|
Packit |
5bd3a9 |
currently defined and any (current or new) keys for that modifier are
