Welcome to the thread, @tobinsbev.
Right now in QuickBooks Desktop for Mac, the way to stop quickbooks from saving an invoice when you scroll up isn't an option. I can see how this feature would be beneficial to you and other businesses. Rest assured, I'll forward this idea on to our Product Development Team for further review.
In the meantime, allow me to share these resources to help you be more familiar with the features and functions available in QuickBooks Desktop for Mac.
I'm just around if you have any other QuickBooks related questions, just leave a comment below. Take care.
