Snap Override lets you supersede all the currently
selected snap types and temporarily use only one,
or none, of the snap types currently selected on the
Grid and Snap Settings dialog. For example, you

the midpoint of an object.

active snap types via a keyboard shor tcut instead
of using the quad menu. Press
Alt+S repeatedly
to choose the override snap t y pe. If the Grid and
Snap dia log is displayed, the "O verr ide OFF" label
