One-Hand Keyboard: Free One-hand Typing is a keyboard utility. It is an app that changes the way your keyboard behaves. It was designed to be used with one hand. I have had injuries that prevented me from using only a finger on one of my hands, and that alone didn't let me type right. A one-handed keyboard is a great idea, but as you may expect, it takes some time getting used to.
This free app is only a "trial" version of the paid one, and it is limited. It will only let you type with one hand within the Instructions window that you can access from the menubar icon. This window shows the layout of the keyboard. Basically, the way it works is by splitting your keyboard in two. One for the right hand and the other for the left. Each key on each side lets you type two letters. For example, the "p" key on your keyboard will input the "p" letter when the Caps Lock is off, and the "q" when it is on. If you want to do an uppercase "p", you just have to hold down the shift key. One of the ways in which the app helps you when you type is by predicting what you are trying to type and suggesting words while you type. This feature works well, all you have to do is to press the "Tab" key to switch among the available options.
