I apologise for upsetting you. I am a complete newbie to this so please assume that currently, I know nothing.
I Am however learning fast. I did not look at the manual because I was using help which is at the top of the list and so far I have found nothing that I was looking for on other subjects, so there is a tendency to give up with it. I must be using the wrong terminology or something. However I have not searched for Object Modes before I have now and found it in both. However the Manual looks easier to follow than the help and Hallelujah, I have been able to select Normal Mode.
So, Thank you for your answers to date, including this one. They have been most helpful to a complete newbie.
