Помогите с sawfish!

Пытаюсь написать функцию для скрытия/показа переодически используемых окон. Пишу так:(в sawfish-client) user> (get-window-by-name '"xterm") #<window e00010> user> (hide-window get-window-by-name '"xterm") user> (hide-window 'get-window-by-name '"xterm") user> (get-window-by-name '"xterm") #<window e00010> user> (hide-window '(get-window-by-name '"xterm")) user> (hide-window '(get-window-by-name '"xterm")) user> (shade-window '(get-window-by-name '"xterm")) user> (shade-window '"(get-window-by-name '"xterm")") user> (shade-window '"(get-window-by-name '"xterm")") user> (shade-window '(get-window-by-name '"xterm")) Никак не срабатывает. Помогите!
