Here is a quick way to mark email messages as read in Gmail. Sometimes I receive multiple emails from students containing assignments–I do not want to take the time to open each message to mark it as read, but I know I can’t read/grade the emails until later. Since I like my inbox to read 0 New Messages as often as possible I will go to my Gmail inbox and place a checkmark to the left of multiple emails as desired. Next PC users would right click; Mac users would press control and click or press the trackpad with two fingers on one of the emails to get the right click menu to appear. The menu below will appear and you can select Mark as read. The opposite also works–you can use this method to Mark a Message as Unread.
