Wow, Google’s Smart Compose Feature (while creepy) is super useful to complete emails faster. To use the suggest text (showed here greyed out) just click the tab button, and it fills in. Truely amazing.
Here is some description from “The Verge” regarding the feature:
Google unveiled Gmail’s new Smart Compose feature at its annual developer conference this week, and it’s now available to try out as an “experimental feature” on desktop. Smart Compose builds off the idea of Smart Reply, predicting what you’ll write next as you type in the body of an email.
To turn on Smart Compose, make sure you’re using the new Gmail, then click on the Settings tab in the top right corner. Within this panel, click the box next to “enable experimental access,” and then save your changes at the bottom. Once turned on, you should see a prompt the next time you begin a new email that tells you about Smart Compose and prompts you to press the tab key whenever you see a prediction you’d like to accept.
