The iPad virtual keyboard is almost as big as a standard-sized keyboard. Still, using a physical keyboard - such as the Apple Wireless Keyboard - with an iPad offers a number of additional features and conveniences - including, of course, the ability to type faster and with more accuracy.
You can use keyboard shortcuts for common editing tasks such as Undo (command key + 'z'), Copy (command key + 'c') and Paste (command key + 'v').
When editing text, using arrow keys is much easier and bit more accurate than using your finger to slide the cursor to exactly the right position.
Punctuations, Symbols and Numbers
Quotation marks, apostrophes, angle brackets, parentheses, plus sign and other punctuations and symbols are much easier to type on a physical keyboard. Numbers, too.
Keys that control sound volume and screen brightness work with iPad. The play/pause, rewind and fast forward keys (F7, F8 and F9) on the Apple Wireless Keyboard work to control the iPod and Videos apps, too.
How to Connect a Bluetooth Keyboard to iPad
Turn on the Bluetooth keyboard. Then, on your iPad, open the Settings app. Tap General and then tap Bluetooth. Make sure Bluetooth is turned on. After a moment, you'll see your keyboard listed. Tap it.
Your iPad will ask you to type a passcode on your keyboard. After you do this, your keyboard will be connected to your iPad.
