Junk Yard · Cards, notes and editing
Can I zoom into an image in the Junk Yard preview?
Short answer: Yes. In the preview, ⌘+ zooms in, ⌘− zooms out and ⌘0 zooms to fit; you can also resize the preview window.
Yes. In the preview, zoom in with ⌘+ and out with ⌘−, and press ⌘0 to zoom back to fit. You can also resize the preview window itself to give the picture more room.
It's handy for reading small print in a screenshot before you paste it somewhere. Zooming only changes how the image is shown — to actually crop or adjust it, use Edit, which saves the result as a new scrap.
