Skip Mac Mojave Screenshot Delay

When you take a screenshot with Mojave using Command+Shift+3, 4 or 5, you get a thumbnail of the image in the lower right corner for a few seconds. This can be handy if you want to access the image by clicking it, without needing to find the file. But if you’d rather not have the thumbnail, you can turn it off. Use Command+Shift+5 and then click on the Options button that appears in the controls. Then uncheck Show Floating Thumbnail.
