In the past, there were keyboards with various letters and numbers, making typing difficult. No longer. Google engineers today introduced a new way of composing your messages using just two keys, a period (.) And a dash (-), which replace all the previous 26: it’s Gmail Tap.
With productivity in mind, there is also a double entry mode that allows you to write up to two different messages for different senders.
If you have an Android device, you can download the Gmail Tap app for free on Google Play.
