Most Web browsers support jumping to specific links through the use of keyboard shortcuts that can be defined on the Web site. Access keys are defined because not all users are able to use a mouse, and several alternative browsing devices do not employ a 'point and click' interface.
Access Key Use
In Microsoft Internet Explorer, the access key is ALT + Access key (You will need to press return to follow the link)
In Mozilla Firefox 1.5 and before the access key is ALT + Access key
In Mozilla Firefox 2.0 and beyond the access key is ALT + SHIFT + Access key
