The other day I was working on some slides for a user group presentation when I hit an issue. PowerPoint's "random slide design" tool had thrown up a style I liked and wanted to reuse. But there were things it added to the slide I could not select. And hence I couldn't see a way to copy them so different slide types could share the same look. It took me a while to work out how to sort this, so it needs writing down so I can remember for next time...
