Normally we focus on keyboard shortcuts, but DRAG AND DROP is a neat way of using your MOUSE!
EXAMPLE: EMAIL ATTACHMENTS
Need to add a file attachment to an email?
Don't bother with all those commands inside your email software. Try a drag and drop--it's much faster. Here's how:
1) Minimize your message window (so it is seen only in the TASKBAR - normally at the bottom of the screen)
2) Locate the file you want to attach (for example, on the desktop or in a folder)
3) Select the file (highlight or click on it)
4) Without letting go of the button, drag the file(s) to the email message item in your taskbar.
Hold the mouse there for a second until the window opens, then drop the file(s) inside the attachment space.
