KeySwitch is a basic key remapping utility which remaps keys on an app by app basis. Simply choose the program whos keys you would like to remap then add any number of key swaps. The best example of what to use KeySwitch for is the Capture application (Camera or Camcorder). Simply adding the Capture application then remapping the side key to the 5-way center key allows you to take pictures using the side key (in addition to the center key still). In fact, the Capture application is added to your list automatically if there are no other programs in the list.
