Tipster Kevin Bradberry shares a tip about using the middle mouse button (the scroll wheel) in AutoCAD.

"Double-click the middle mouse button to perform a Zoom Extents. I don't think I've seen others using this, so I thought it might not be well known. I use it constantly, along with zooming in and out by rolling the mouse wheel, to the detriment of all the options located within the Zoom command (meaning that I forget to use the other zoom commands)."

Notes from Cadalyst Tip Reviewer Brian Benton: You never know what other users know or don’t know. I worked at one office where employees never double-clicked the scroll wheel on the mouse, because many years ago that action was set in the company standards to do something else. It was that way for so long that many users didn’t know you could use it to perform a Zoom Extents.

You can program the mouse buttons to do anything in the CUI (Command User Interface); if you don’t want to Zoom Extents, simply change the way it works.
