In MacOS Mojave, when I take a screenshot with CMD + SHIFT + 4
(so this isn't a normal screen shot, it's a screenshot of a little part of my screen), it takes several seconds before it's saved. Actually, the OS allows me to click on my screenshot and edit it for instance.
But what if I want it to be immediatly saved after I took the screenshot with a shortcut Keyboard ? (This feature changed in MacOS Mojave, before this version of MacOS, the screenshot was indeed imemediatly saved).
This question explains how to permanently remove the waiting, but what if I want to remove it on particular moment and not always ?
