Need to enter two or three capital letters in a row? If you’re using a standard computer keyboard or an old manual or electric typewriter you can do this by engaging the Caps Lock, typing the letters, and disengaging the Caps Lock. Of course, if you’re just typing two or three letters, it’s easier to hold down the Shift key and type. Most mobile touchscreen devices with “soft” (on screen) keyboards don’t let you do this. However, the keyboard on the iPhone and iPod touch does.
