vcursor-find-window
vcursor-find-window is a compiled Lisp function in `vcursor.el
'.
(vcursor-find-window &optional NOT-THIS NEW-WIN THIS-FRAME)
Return a suitable window for displaying the virtual cursor.
This is the first window in cyclic order where the vcursor is visible.
With optional NOT-THIS non-nil never return the current window.
With NEW-WIN non-nil, display the virtual cursor buffer in another
window if the virtual cursor is not currently visible (note, however,
that this function never changes `window-point').
With THIS-FRAME non-nil, don't search other frames for a new window
(though if the vcursor is already off-frame then its current window is
always considered, and the value of `pop-up-frames' is always respected).
Returns nil if the virtual cursor is not visible anywhere suitable.
Set `vcursor-window' to the returned value as a side effect.
