DESCRIPTION
XkbLockModifiers sends a request to the server to lock the real modi-
fiers selected by both affect and values and to unlock the real modi-
fiers selected by affect, but not selected by values. XkbLockModifiers
does not wait for a reply from the server. It returns True if the re-
quest 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:
