Surfing webpages always requires you to use the mouse to select text or click on links etc, now compare this with a text file or document where u can easily move around in the page using your arrow keys. The idea behind allowing users to browse webpages using keyboards is also known as Caret Navigation. According to wikipedia:
In computing, caret navigation is a kind of keyboard navigation where a caret (also known as "text cursor", "text insertion cursor", or "text selection cursor") is used to navigate within a text document. It is a fundamental feature for applications that deal with text, for example text editors, word processors and desktop publishing programs
If you would like to surf webpages the same way, you can easily accomplish it easily in Firefox and Internet Explorer.
Caret browsing is definitely useful for mouse-less browsing of webpages, along with a easy way to select text and click on links on a webpage. If you are looking to move to caret browsing, here is a simple way in which you can turn on caret browsing in Firefox and IE 8.

Firefox provides users with a hotkey to toggle between caret and regular browsing, pressing the F7 hotkey will display a dialog which will alert you about entering caret browsing mode, to disable this dialog from appearing everytime, select the option to not display the dialog box again.
