Keep your clicking finger here when not in use. To click, bear down momentarily with your index finger on the left mouse button. If you hear a separate click as the button cheers itself up, your click generally won't register. The important thing is to find what's comfortable so you can relax and stop worrying about the mouse and do and what you came here to do. You need to mouse to point to links and the mouse button to follow these links.
Links can either be text or images .
Imagemaps are special images that are divided into regions, clicking in one of which leads to a different destination. The bar near the bottom of the Library's home page is one example of an imagemap. Text links are usually represented in a color different from plain text. This is the chief clue used to identify a link. The cursor also gives a clue about links.
