I just got an heavily commented pdf, when I open it in Preview, all annotations (highlights, notes) are "hidden", i.e. do not show up in the left margin. I can display them by clicking on them but I would like to see them all at once without having to click on each of them individually. I couldn't find a menu item but maybe I missed it? Or is there a keyboard shortcut?
This is a workaround, as I couldn't find a hotkey or menu option to do this. Still, clicking
Will show all anotations. I can now see all the annotations without manually clicking them. This worked on Preview 5.5.1.
