I love the "CTRL-ENTER" shortcut in Internet Explorer.
That is, if you want to go to a www dot com website, like http://www.microsoft.com for instance, just type Microsoft in the address bar, and then press CTRL and ENTER at the same time. The "Microsoft" will be wrapped with "http://www." and ".com".
Well, every now and then, I would mistype the CTRL-ENTER part, and the contents of the address bar would shift to be right-aligned (for Right-to-Left reading). I could never figure out what keys I pressed, because it would always happen so fast.
This morning, I finally figured it out. CTRL-Right Shift (the one right under the ENTER key) will shift to RTL reading order, and CTRL-Left Shift will return to LTR reading order. Note that there's also a right-click context menu on the address bar combo box that allows you to do the same thing.
Now I don't have to assume that my laptop is possessed by mischievous demons.
