When you click on that tiny icon, it alternately toggles pointing left and down, but what does it do? Also, why is there no discussion of the “popup message” when I search for it in Help? Maybe it’s called something else, but it’s what Avast calls it in the right-click tray icon menu.
It is a " pin " if you click it you will pin the popup to the screen…if you need moore time to read it or want to take a screenshot…
