I do know how to access the cursor pad, and it works fine for me on the iPad, but not so much on the iPad Mini. It occurred to me that it may be behind the keyboard, related to the text editing issue.
Yes I can scroll to the last several lines, but they snap back behind the keyboard.
The 'files' pop-up also extends below the top of the keyboard (unlike the expected behaviour I see on the iPad) requiring me to close the keyboard to access the file tools.
This does appear to be only an iPad Mini issue.
