font body all documents in project all of a sudden set to microscopic size 2

I pressed a keyboard shortcut by mistake (don’t know which one) and all of a sudden the default font of the body of all documents in the project excluding headings is set to size 2.
How is that possible ? In control panel, none of the styles are set to size 2.
How can I reset the size to my usual arial 13 black ?
thank you very much

It’s difficult to guess what you may have done but this article covers how to get everything back to how you like it: … my-project

I figured out the problem. I gave the Scrivener Scratchpad the same global shortcut as a local shortcut heading. thanks very much for your comment ! Sorry for taking your time for such a basic mistake.
