Use bidirectional text in Keynote on iPad
Keynote supports bidirectional text, so you can enter and edit text written from left to right (such as in English or Chinese) and from right to left (such as in Arabic or Hebrew) in the same presentation. To use bidirectional text, you must have at least one right-to-left language in your device’s preferred language list. To learn more, see Set up a keyboard or other input source for another language.
Note: You can use any Keynote theme to create a bidirectional presentation, but to see themes designed specifically for another language, you must set the primary language of your device to that language (go to Settings 
> General > Language & Region, then set the language). When you create a new presentation, you see themes for that language.
