This is a simple animation, once you learn GA 5's tools.

Part of the typewriter was copied and pasted to make a new object to cover the paper. Text was made then split with the "Split Text" command.

A blank frame was added with just the paper and text, then the Flatten Frame as Single object was used to combine the text and paper. This made moving the paper and text up easier. That frame then had the rest of the objects added.
