Have you ever wanted to pick objects that are outside of a window area? Select Outside of Window (Tip #2173) from Sanjay Kulkarni may be just what you've been looking for. Load the LISP code into AutoCAD, and the new selection feature becomes available. When you start a command such as Copy or Erase, a modified prompt appears informing you that options WO and CO are now available during selection. These work just like the normal inclusive and crossing window, except that objects outside of the box are selected instead of those inside. Sanjay employed a command reactor to get the prompt to appear when you start a command, and this is a great example of how you can juice up AutoCAD to fit your needs.
