When browsing photos I can use the space bar to open the photo preview.
It would be very useful if pressing space bar would allow to close the preview window. that way I could previewing photos with only pressing the space bar.
Thanks and regards
Edit - Just heard back, and the reason that doesn't work is because the spacebar is already being used in Zoom mode for panning. Since the zoom-pan combo is how other photo editing software works, we thought it would be confusing to use a different key for that.
