Recording over errors

I am trying to record stories for my grandchildren to listen to. If I make a mistake I want to be able to record over it and continue recording from where I broke off. Have looked at the online manual but can’t find a reference to how to do it. If I select the error delete it and try to resumed recording it goes into playback.
What am I doing wrong?

Stumbled across an answer - Shift R.
Sorry to be useless!!!
