Regardless of which section you have selected and which buttons you have pushed, the screenshot will automatically be saved on your desktop as a PNG image file. The naming of the file is also done automatically by the operating system – all files names begin with the word ‘Screenshot’ followed by the time and date that it was created.
If you would prefer that a screenshot on your Mac does not directly turn into a file and instead is copied onto the clipboard (as is the standard with screenshots with Windows), then this is also possible: by additionally pressing the [Ctrl] button the Mac will store the screen grab in the clipboard. From here it is easier to transfer it to a word and image processing program that you might be working with. This process works with all Mac screenshot shortcuts.
