I usually use the Opera browser for administrative purposes as part of my work. Firefox and Internet Explorer are relugated to their status as test browsers.

Anyhow, while madly clicking away on the Opera window, I noticed the pages would jump back and forth. Turns out that holding down the right button while clicking the left button will go back one page and vice versa for holding down the left button while clicking the right button.

Improvements upon the user interface continue to make large strides forward!
