Scroll and zoom by using the Microsoft IntelliMouse pointing device

You can move around and zoom in the workspace by using the Microsoft IntelliMouse pointing device. For information about changing options and viewing troubleshooting tips for the Microsoft IntelliMouse, see the IntelliPoint Online User's Guide. (In most cases, you'll find the User's Guide by clicking the Windows Start button, pointing to Programs, and then pointing to Microsoft Input Devices.)

To	Do this
Pan the workspace in any direction.	Hold down the wheel button, and drag the pointer away from the origin mark in the direction you want to scroll. To speed up scrolling, drag away from the origin mark; to slow down scrolling, drag toward the origin mark.
Zoom in or out on the workspace.	Rotate the IntelliMouse wheel forward or back.

Tips  

• By default, rotating the wheel button in the workspace zooms instead of scrolls. If you use the Microsoft IntelliMouse pointing device to scroll more often than you use it to zoom, you can set the wheel button to scroll by default. On the Tools menu, click Options, click the General tab, and then click Scroll under Mouse and keyboard.
  
  
• You can press the CTRL key while rotating the wheel to quickly switch between zooming and panning.
