With `M-:' you can evaluate arbitrary lisp code which has access to the current environment (buffer with point and mark, window, etc.) where you hit `M-:'. So in your case M-: (window-height) should do the trick. (BTW: With M-TAB you have autocompletion for any known lisp symbol there.) Bye, Tassilo -- Richard Stallman gets 9 bits to the byte.
