:thumbup: Welcome to TPF Ralph! :camera:
A key that will help with the confusion is to carefully read the camera's users manual, with the camera close at hand so you can play with each feature as you read about it.
It's dry reading and it takes a while to get all the way through the first time.
By then you'll be familiar with how the manual is organized and you'll know where the Index is, which will help you refer back to sections that you'll later want to revisit.
