Mark Wagner demonstrate a Chrome extension that could completely change my attitude toward email. Popchrom is a Chrome extension that allows you to create keyboard shortcuts for inserting large chunks of text into an email. So instead of retyping a message you can simply hit your keyboard shortcut and insert a big chunk of text.
Here's how Popchrom works; after you install the extension you can type out your chunks of text in the Popchrom settings and assign a keyboard shortcut for those chunks.
Applications for Education
If you often type the same type of message to parents, students, or others, Popchrom could save you tons of time.
