Now you just need to find a few creative ways to use your new external keyboard buttons. The simplest application is to just use it to scroll through Reddit or to start and stop your music player. Or you can use it or gaming. That way you can control character movement, aim and hit commands all at the same time. You can also use it to help data logging. You can easily count the number of times that an event happens using a spreadsheet. Just count the number of times that a letter is typed. This design also makes it easy to set up controls for people with limited mobility.



The only down side of this design is that you can't use that key on the keyboard while the external switch is attached. So if you want to be able to still type on the keyboard like normal, then you need to two keyboards. One will let you type and the other will have the external switches connected. This shouldn't be too much of a problem because you can get cheap keyboards at a thrift store and most computers have plenty of extra USB ports to use.
