Using Voice Typing on Docs
This feature has been around for a while, but is often times overlooked. Docs has a free, and built in, option to use your voice to type. It's a lot like using the voice to text option on your phone. This could be used to save you time, or it's a feature students could use (every now and again) to quickly complete an assignment.
*You will want to go through and edit the Doc though, since it isn't always perfect!*
