[iMore Question]

I keep accidentally moving/ even deleteing appointments on the icalendar - then don't know where I moved them from and don't know how to reverse the step.

All I can advise is for you to be a bit more careful when using the Calendar app on your iPad. As for reversing a deleted appointment/event, I could be mistaken, but I don't think there is an undo option for it in iOS. I've never had to undo a deletion of a calendar event on my iOS devices so I haven't had the need to seek that option.
