If you wish your keyboard's keys were laid out just a tad bit differently, you can change it around with a keyboard remapper. Windows users have a few to choose from, but the easiest to use is certainly KeyTweak, which presents you with a full, visual keyboard layout and multiple methods for changing it.
Update: KeyTweak's home page seems to be down, with no indication of whether the program has been abandoned or anything. However, it's still available from software sites like Major Geeks, so we've updated our link to the download page below.
