XkbLatchModifiers sends a request to the server to latch the real modifiers selected by both affect and values and to unlatch the real modifiers selected by affect , but not selected by values.

XkbLatchModifiers 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:

True

The XkbLatchModifiers function returns True if a request was sent to the server to latch the real modifiers selected by both affect and values and to unlatch the real modifiers selected by affect , but not selected by values.

False

The XkbLatchModifiers function returns False if the request was not sent.
