You can turn on handwriting recognition in Gmail now. Go to settings, general tab. Enable input tools. Go back and start writing an email. There’s a new button on the upper right, between the pagination and settings gear. Click it and a window appears for you to draw in.
Gmail and Docs offer wide language support, however in some cases using the keyboard is less than ideal. Whether you’re a student trying to include a foreign phrase in your paper or an international consultant hoping to begin your message with a friendly local greeting, now you’ll be able to use your own handwriting to input words directly into Gmail and Google Docs with your mouse or trackpad.
