If email is your communication method of choice, the faster it is to compose messages the better. One thing I find myself doing quite a bit is attaching/embedding images (screenshots) and files.

If you use Outlook and your text formatting is either RTF or HTML, did you know you can paste copied files and images directly into the message via Ctrl+V? I find this incredibily useful, especially when it comes to screenshots. Since they are copied to my clipboard, I don’t have to save them to a file first before I can get them in an email. Web-based clients do not have this functionality as you have to browse to and manually attach each file.

I am sure this functionality exists in many other email clients as well, so if your client of choice does this, please share.
