;; Let the user pick a window with the mouse, and then evaluate some
|
|
;; expression on that window.
|
|
;; The basic function is "(pick-window)", which lets the user pick a
|
|
;; window, and returns the wob number. It considers the variable
|
|
;; "cursor".
|
|
;; More advanced functions are "(with-picked EXPR)" which runs EXPR
|
|
;; on the picked window, and "(kill-picked)" which deletes the picked
|
|
;; window. Calls to these can for example be done from a root menu.
