Keep, with a hollow star, and a line underneath: keep to save this to Marks.

Press it and the star fills.

Saved to Marks, with a link straight there.

Back in the text, the line under the phrase has gone solid.

That is how you tell a suggestion from something you decided to keep.

Changed your mind?

Press Kept a second time and it steps back to a suggestion, with the annotation still there.

View takes you to Marks: the highlights you made, and the annotations you kept, gathered from your reading.

Down the side: All, Highlights, Annotations, Notes.

Annotations here means the ones you chose to keep, so this page stays yours.

Select the row and a drawer comes in from the right.

In context: the article around the mark, with your span lit inside it.

Open article, and you are back on the exact span, in the piece it came from, and it flashes once so you can see where you landed.

The page stops at five hundred marks, which is a great deal of reading.

A mark stays on the paragraph that earned it.
