EZ Keys is an application developed by Words+, that helps users with a wide range of disabilities to communicate. After you type the initial letter(s) of a word, you will be able to select it from a list provided by the program. The word will be typed automatically. All you need to do after you install it, is to launch it, to begin typing the word you want to use and to select it from the provided list. Also, you can edit this list by adding and removing any word that you want. If you have problems using the software, I recommend you contact the developers.
