XkbLockModifiers
sends a request to the server to lock the real modifiers selected by
both affect and values and to unlock the real modifiers selected by
affect, but not selected by values. XkbLockModifiers does not wait for
a reply from the server. It returns True if the request was sent, and False
otherwise.
The functions in this section that change the use of modifiers
use a mask in the parameter affect. It is a bitwise inclusive OR of the
legal modifier masks:
