Close Image Preview with Escape Key?

Or is there another shortcut? I often click it open to check the image itself, but there doesn't seem to be a quick way to make this window go away without clicking the X button with the mouse. I'm often using just the keyboard, so a quick way to dismiss this window and go back to the list and continue with the marking of duplicates in a group would be helpful.

Press F4 to turn on and off?

Will check this and add shortcut. F4 is probably the best
