control- command- 3
today I needed to take a screenshot in a MabBook Pro, I typed control-command-3 instead of shift-command-3 and all my desktop symbols suddenly disappeared to one folder, and when I click on it one time, I see all the symbols, but I can't get it back as it was, all the symbols appears in the desktop and not in this folder.
how can I switch it back?
Thank you!
