PowerClicks 1.2 - PowerClicks is a useful Control Panel that does the following things - it can make a key combination act just like the mouse button; it can make another key combination toggle the mouse button on and off; it can disable the real mouse button (in case it's broken); and it can assign graphical effects to mouse clicks. PowerClick is useful if you have to use your PowerBook in a very silent environment, where even a trackball click can be extremely loud. Since the keyboard is a lot more quiet than the trackball button, you'll be able to use your trackball while other people are reading or even sleeping.
