From the iPad Settings App:
- Tap General.
- Tap on Keyboard.
- Tap on Text Replacement.
5. Tap on the + sign in the top right corner.
6. In the Phrase field, type in the entire phrase you'd like to create a shortcut for.
7. In the Shortcut field, type in the snippet you want to be replaced by the phrase.
8. Tap Save at the top right.
Now anytime you type that shortcut, it will replace it with the phrase you designated in the predictive text.
Just tap the space bar to complete the phrase. If you can't select the message, then the phrase is too long.
