======Synopsis:======
[[window]] refnum_or_swap <refnum>

======Description:======
This atomically makes the given window both current and visible,
without failure.  If the window is visible, then the client makes it
current, as [[window refnum]] would do.  If the window is hidden, then
the client swaps the window in and makes it current, as [[window swap]]
would do.  This action never fails unless you specify a window
that doesn't exist.

======History:======
This operation first appeared in EPIC4pre2.001.
