I figured that little trick out a couple of months ago, but it doesn't work on every page, and it doesn't always stay that way. For instance, if I blow up the text on my home page and then leave, when I return home, the text may, or may not, be the same size when I left. I use that shortcut dependent upon the monitor I am viewing on. Good info though.
Another trick is to click your wheel, and you can scroll through a page without having to roll the wheel.
I think some pages, if you use, oh hell what is it, ctrl A, or Alt A, it changes the text font color to white?
EDIT: I just tried it and it didn't work with either. I'll try to figure out what it is. Used it to change font color on a page with black background and grey lettering that was really hard to see one time.
