Answer 1

Alternatively referred to as Control+O and C-o, Ctrl+O is a keyboard shortcut most often used to open a URL, document, image, or other file types. This page covers the Ctrl+O (letter 'O') shortcut and not the Ctrl+0 (zero) shortcut. On Apple computers, the keyboard shortcut to open is Command + O.
