This information applies to Windows Internet Explorer 8.
Rather than using a mouse to select text and move around within a webpage, you can use standard navigation keys on your keyboard—HOME, END, PAGE UP, PAGE DOWN, and the arrow keys. This feature is called Caret Browsing and is named after the caret—or cursor—that appears when you edit a document.
Open Internet Explorer by clicking the Start button , and then clicking Internet Explorer.
Do one of the following:
Click the Page button, and then click Caret Browsing.
Click Yes to turn on Caret Browsing.
Click the Tools button, and then click Internet Options.
Click the Advanced tab.
Under Accessibility, select the Enable Caret Browsing for new windows and tabs check box, and then click OK.
