Is there a secret key I don’t know about?

I recently updated the iOS on my iPad Air. What I have noticed to some dismay is that I will be typing away trying to place a post here on ehMac when all of a sudden my chubby little fingers must hit some magic key combination and my complete text vanishes......is there some key combination on the iPad that deletes text? I’ve looked on line but can only find shortcuts for regular Mac. I do know it must live around the space bar.
