Damnit was just about to post cause I thought I'd just found two by accident then I saw this!
Anyway, what I thought I'd just discovered was...
In Internet Explorer, hold "shift" and scroll the mousewheel - scrolls forward and back through viewed pages without pressing the back and forward buttons on the IE toolbar, and
Hold "ctrl" and scroll the mousewheel and it changes the font size in the selected window, regardless of application.
