Is there a word similar to "encircled", but meaning "to surround in a rectangle or a quadrilateral", instead of a circle?

When I show screenshots and I want those who see the screenshot to focus on the area of the screenshot I marked as surrounded with a quadrilateral (usually a rectangle), I would say "see the area encircled in red".

It turns out that this is an incorrect usage of the word "encircled", as it means "to surround somebody/something completely in a circle".

framed - put in a frame, usually rectangular. Framed in red would be probably what you need.

Boxed-in - enclosed in or as if in a box.

Without being so precise, you could be less precise, and speak about the highlighted area, or focussed...

With more information, you could say, "Remember the name in the blue highlighted area," if you surrounded it with a blue rectangle.
