Q

When it comes to interacting with a mouse in Windows, there are three possibilities: pg 573

A

**Primary mouse click—A single click (typically the left mouse button) used to select an object or place a cursor.
**Double-click—Two primary mouse clicks in quick succession. Used to open a program through an icon or for other application-specific functions.
**Secondary mouse click (or alternate click)—Most mice have two buttons. Clicking once on the secondary button (usually the one on the right, although that can
be modified) is interpreted differently from a left mouse click. Generally, in Windows this click displays a context-sensitive menu from which you can perform
tasks or view object properties.
