Is there any way to enable Dvorak on iPad for apps like Pages or Notes?
Kind of a yes, no - the software keyboard can only ever be QWERTY, AZERTY, or QWERTZ. However a hardware keyboard hooked up via Bluetooth, or dock connector (or USB with the camera connector) can be set to use DVORAK:
- Open up Settings App
- Go to General
- Select International Keyboards
- Select your English Keyboard
- Under the Choose a Hardware Keyboard Layout you can select DVORAK.
