I am a hotlink to page 2. Each time you click on this button you will go back to the previous link you have used. If you click on this and hold the mouse button down you will see all the steps in the path you have recently followed and can go directly to any location by selecting it and releasing the mouse button. The most recent location is at the top of the list and the current location is indicated by a checkmark. The color change is a useful navigation aid to help you keep track of where you have been, but does not affect the operation of the hotlink in any way.
Graphics can also serve as hotlinks.
The graphic in the center has a hotlink which behaves in a similar manner to the text hotlink you used before - namely when you click on it it performs one single action. It detects exactly where you click in the image and can be programmed to take many different actions according to that location. For example, you could get a different action by clicking on one eye or the other or the mouth etc. An easy way to determine whether a graphic has a hotlink and which kind it has is to move the cursor over the graphic. If the URL shows numbers at the end which change as you move the cursor around in the graphic then the graphic is an imagemap, otherwise it is a normal hotlink.
