Many of the Ribbon Panels in AutoCAD 2016 have more than meets the eye. Want to see more of the menu… Try This:
Click the little down arrow at the bottom of the Ribbon.
[1]
This will drop down the additional menu items.
[2]
Click on the Pin and it will hold the menu open for you.
[3]
Once you navigate away from that Ribbon Tab and swap Ribbon Panels, it will close back up and not be open when you return. Sure wish there was a way to make it sticky.
