Can someone undo the cover on my saved image?

No. The saved image is flattened, so the covered pixels are replaced, not layered on top. Use solid covers, not blur, for anything private.

Can I use it without a mouse?

Yes. Tab moves between the objects on the screenshot, arrow keys move the selected one, and Alt with the arrow keys resizes it.

Solid covers replace the pixels, so the hidden text can't be recovered from the saved image.
