OBJECT SNAPS (OSNAP):

OSNAPs allows you to select positions on components in a drawing for locating other features.

OR

typing an Osnap alias on the prompt line when needed (SEE EXPLANATION BELOW).

When an Osnap is used, the CURSOR changes shape when it is near a position that matches the Osnap selected and "snaps" to that point. The cursor shape differs with each Osnap.

*NOTE: Although you can set an Osnap(s) to stays active all the time (select Running Object Snaps under the Tools Menu), this should only be used for repetitive snap constructions. If you forget to turn the Osnap off and start a new task, you end up snapping to the wrong features.
