Pages iOS, shortcut next cell, external keyboard, when in table

Hey people,

When looking for the answer online, I couldn't find a website with a helpful answer. However, if it was asked before, my apologies.

I'm currently using my iPad (4th generation) in combination with an Apple Wireless Keyboard. When using Pages, I noticed some of the keyboards, but not all - such as jumping to the next cell when editing a cell. What's the shortcut for that, and/or is there a manual available displaying all the shortcuts for Pages in iOS?

Thank you!
