Kern from the Keyboard

Adjusting the space between a pair of letters is known as kerning (yes, you probably knew that, but we needed to be sure). To adjust the kerning between two letters, click between the two letters with the Type tool (T), press-and-hold the Option key (PC: Alt key), and use the Right Arrow key to increase the kerning or the Left Arrow key to decrease the kerning. To change the kerning using larger increments, add in the Command key (PC: Control key), making the shortcut Command-Option-Right (or Left) Arrow key (PC: Control-Alt-Right [or Left] Arrow key), depending on whether you're increasing or decreasing the kerning.
