One feature of Windows I can't live without is the context menu (brought up by right clicking on the mouse). Just imagine what you would do if you lost this service all of a sudden because a mouse died for some reason... Luckily this function can be done with the keyboard too - as long as you know the trick. ;-)
It's pretty easy to bring up the context menu on the keyboard, all you have to press is Shift + F10 and you're set. Use the directional keys on the keyboard to scroll through the different options and you should be set. This tip is great for those of you who are more the keyboard type, and would prefer not to use the mouse as much.
