Google Keep is one of the lesser-known members of the Google Family. It is similar to MS OneNote or even the Windows Sticky Notes. When I opened up a document that someone had shared with me today, I followed a pop-up tip that showed me that you could drag and drop comments from Google Keep into the document. This might be a great way to save common comments and just drag them in. What an easy way for teachers to grade papers! Just put common errors or comments into a note in Google Keep, and drag over to grade and comment on the paper! Give it a try!
