"Sticks" a floating window to the current output so that it shows up on all

*swap* container with id|con\_id|mark <arg>
Swaps the position, geometry, and fullscreen status of two containers. The
first container can be selected either by criteria or focus. The second
container can be selected by _id_, _con\_id_, or _mark_. _id_ can only be
used with xwayland views. If the first container has focus, it will retain
focus unless it is moved to a different workspace or the second container
becomes fullscreen on the same workspace as the first container. In either
of those cases, the second container will gain focus.
The following commands may be used either in the configuration file or at
runtime.
