Oh Snap!

Object snaps are really important in AutoCAD and in addition to the running object snaps, many AutoCAD users have the Object Snap toolbar permanently docked on their screen. However, as screen space is often at a premium, you might like to consider accessing the object snaps from the Shift + Right-click menu.

​If you didn't know about this, you'll find that it's even better than the Object Snap toolbar because it takes up no space and it contains all the object snaps including "Mid Between 2 Points" and the Point Filters.
