Excellent Macintosh pintware utility created by Turlough O'Connor. It adds a great deal of functionality to Mac OS 8's contextual menus, allowing you to bring up a menu simply by holding down your mouse button (rather than having to hold down a modifier key, or get a multi-button mouse). You can add your own extensions to the menus, allowing you to do nifty things like change file types instantly.
