LIGHTKEY IN THE PRESS

You know how convenient it is when you start typing a search phrase in Google and it knows what you're thinking? Or when your phone suggests the word to insert so you can save time pecking at the keys? LightKey is like that but for your computer. Once you have the app installed, LightKey will start suggesting words as you type. It's predictive text, not autocorrect, so you don't have to deal with autocorrect fails. But by simply clicking the Tab key, you can accept the word and start typing at lightning speed. The program takes into consideration specialized words you might use for your industry, such as technology or healthcare, and learns from your most-typed words and phrases. It works in Word, PowerPoint, and Outlook, as well as Gmail (Chrome extension required) and a few other mail and chat programs.
