What is the syringe-like icon which appears on all plasma pages in the "title bar" at the top of the page, second place on the left? And what exactly is its function? When I left click on it, it turns into a small white disk with a dot in the centre. If I click on it again, it turns back to the syringe icon. When I right click on it, nothing happens.
It's not a syringe, but a pin :-) When you click it, it pins the window to all virtual desktops.
Thanks, I see now that it does look like what I know as a mapping pin. And I was trying to work out what was in the syringe!
More generally, is there a page online somewhere that outlines the anatomy of a plasma page?
There's https://userbase.kde.org/KWin but I'm not sure how much up-to-date it is.
Thanks again, that is quite interesting. But as you suggested it seems rather out-of-date. I don't see anything remotely like Workspace Appearance -> Window Decorations -> Configure Buttons (which would presumably have told me what the different buttons mean) in my System Settings. The nearest I can get is Appearance -> Application Style -> Window Decorations where there is a screenshot with Configure Buttons in it, but no indication how to get there in real life.
