To use zoom
The mouse wheel performs zoom. Zoom either magnifies or demagnifies a document. This feature only works in Windows 95, Windows 98 and Windows 2000 compatible applications that support zoom.
1. Place the cursor in compatible application or window that supports zoom.
2. Press and hold the Ctrl key, and at the same time, do one of the following:
To zoom in, move the scroller or your finger forward.
To zoom out, move the scroller or your finger back.
Note: You can also assign the Ctrl key to a mouse button and click the button assigned to the Ctrl key function before using Zoom.
