If there are any rich-edit-panes (instances of the
rich-edit-pane class) on parent-window that have
had the keyboard focus, then the rich-edit-pane on parent-window that
most recently had the focus is returned. (This will be the one that
has the focus now if one does.) Otherwise the parent window of
parent-window (if it has a parent window) is similarly searched,
returning the most-recently-focused rich-edit-pane if any, and then
the parent of that window (if any) is searched and so on through the
top-level window. (Whenever the parent-window is a
frame-with-single-child window, the
frame-childframe-child of the parent-window is searched.) If no
rich-edit-pane that has had the keyboard focus is found, then
nil is returned.
This function is chiefly used internally to find the rich-edit-pane
that should be affected by one of the rich-edit "helper" controls such
but could also be used by applications. Searching successive parent
windows allows a helper control to be on a toolbar of the window
containing the rich-edit-pane, for example.
