Quick way to toggle between recent note and pdf?

Hi! New to marginnote and need help!

By accident I “popped up” my current note over my pdf, but I can’t figure out how to do it intentionally. Right now to bring up a note there are many steps, I have to click on the mindmap box, click the write key, and then click the writing tool on the note itself (at which point I’ve forgotten half of what I was going to write and have to start all over). How do I do this?

Do you mean the view that opens when you click on Edit Note Card from the horizontal pop-up menu that appears when you click on a note?

My understanding is that this Edit Note Card view is mainly a shortcut. In the mind-map view, you can just click directly on the notecard text, its title, or the comment(s) below, and edit any of them in place.
