Firefox: In page "Bookmark" tip

When scrolling through a long web page, you sometimes need to refer back to an earlier part of the page. This would entail scrolling back up and visually searching for the reference.

Firefox allows you to enable "cursor key navigation", or "allow selection using the keyboard" in FF 2.0 and 1.5 respectively. Essentially this just means that you have a normal text cursor that you can use in text to cursor around and select text using normal keyboard selection keystrokes (like shift-cursordown will highlight a line).

However, you can also use this as a sort of bookmarking facility. Click the mouse on the text where you want to refer back to, and a blinking cursor will appear.

Now scroll down to read the remainder of the document. If you need to get back to the point where you left the cursor, just hit left or right arrow. All this does is move the cursor you left behind left or right, but ff will also jump back to that position to show you it moving!
