Welcome to iPhone 101, the series that explains the basics of iPhone operation. This time, its enabling caps lock.
It always astounds me how many iPhone users don't know how to enable caps lock while typing, not just newcomers. Just the other day I was chatting with a friend who's had an iPhone for almost a year. I suddenly had to send a quick text message and my friend was bewildered to see me type some of that message in all-capital letters without having to repeatedly hit the shift key for every letter in capital I typed.
Well, to relieve your curiosity and sheer frustration, here's how to type in caps lock on the iPhone keyboard. Simply double tap the shift key. That's it! The shift key will turn blue, and everything you type will be in capital letters. To exit this mode, simply tap the shift key again.
Actually, his confusion is understandable. A QWERTY keyboard has a shift key and a caps lock key, but the iPhone's keyboard merges the two keys into one. Holding a typical shift key will produce a series of capital letters. Yet, holding many of the iOS keys produces a pop-up menu of special characters, symbols and accents. Except for the iOS shift key; holding that down simply registers a single tap. A long, long, tap.
Well, regardless of why, now you know how. And if you already knew how, you might know someone who doesn't. Make their day and share this simple, effective iPhone 101 tip. Bonus: it works the same way on the iPad and the iPod touch.
