How do I get Pages for iOS 7/8 to use the TAB key on a bluetooth Keyboard to change the indent level? So Pages for iOS 7/8 has a software TAB key that changes the indent level of an outline. It also has forward and backward indent keys. Great. 

However, when I press the TAB key on by Apple Wireless Keyboard, all it does is put in a tab character. The TAB key works fine on Pages for my MBP, with Shift-TAB back indenting it. 

Is there a way to get the TAB key on the Wireless Keyboard to work like the software TAB key for iOS?
No. Apple would have to add an additional function for the bluetooth-users, which they hadn't until now. So it's not possible to use the tab-key, because you can't change the button-functions in the iOS-iWork-apps.
