Question: Saving an image to a file

[ltgs]

Hello, I wasn't sure where to ask this question so posting here, but happy to post it somewhere else just let me know.

I wanted to use the "Save image to a file" command (see https://copyq.readthedocs.io/en/latest/images.html#save-image-to-a-file ) but I couldn't figure out how to do it.

Is there an explanation somewhere?
