Like most BlackBerry users I'm a big fan of Auto Text on my device (AKA Word Substitution). You can add an endless supply of quick text expansions that make typing out long or common phrases a breeze. There are quite a few that come preset on the device as well, one of which is "sig". Typing "sig" in any text field will automatically spit out whatever you have entered for your lock screen information (Put in the info by going to Options > Display > Message on Lock Screen). Pretty cool if you want to quickly enter your email address, name or other text without typing it out (mine is set to my email address). Keep in mind too that you can edit the "sig" Auto Text and change it to whatever you'd like should you choose to do so, but it defaults to the lock screen info. Thanks @dannthedude!
