vcursor-window-funcall

vcursor-window-funcall is a compiled Lisp function in `vcursor.el'.

(vcursor-window-funcall FUNC &rest ARGS)

Call FUNC with ARGS ... in a virtual cursor window.
A window other than the currently-selected one will always be used.
The virtual cursor is moved to the value of point when the function
returns.

If FUNC is a list, call the car of the list interactively, ignoring
ARGS. In this case, a new window will not be created if the vcursor
is visible in the current one.
