With only two keys, you can use Gmail Tap to send messages in the Gmail application using just dots and dashes.
Not only that but Google Tap offers a multitasking mode that gives you two Morse code keyboards at once so you can send two different messages to two separate recipients at once.
"I think the people who will be best served by Gmail Tap will be people with fat fingers," says Google engineer Mitch Fedenko in the company's promotional video.
What happens if you have thin fingers? The Gmail gag makes for a good giggle anyways, as you can see here.
