A great feature in Google Docs is the ability to voice type using control shift s. Students really enjoy this feature; however, when you are not on a Google Doc - they can be a bit bummed that it does not work.
What you can do (if you are on a Chromebook) is to go into the accessibility features and select dictation. This will have a microphone appear in the bottom righthand corner of your Chromebook. Make sure to select it and then speak. When finished speaking/typing, make sure to click on it again. While a simple tool, I am sure for many, this will be very helpful.
