iOS 5 introduced a very awesome feature, split keyboard. It wasn’t mentioned much, if at all, but it’s great for browsing or using iMessage while holding the iPad in two hands.
Still, the feature wasn’t widely mentioned, and it isn’t immediately apparent how to get it working, even when you turn the option on.
1) Go to Settings > Keyboard
2) You will see an Option for Split Keyboard. Turn it on.
3) When you enter any app that allows for use of the keyboard, hold the “Hide Keyboard” button.
4) Select “Split” and the keyboard will split, making it much easier to type with your thumbs.
