You can press key combinations to do things on your iMac that you’d normally do with a trackpad, mouse, or other device. Here’s a list of commonly used keyboard shortcuts.
Note: Keyboard shortcuts in apps may vary depending on the language and keyboard layout you’re using on your Mac. If the shortcuts below don’t work as you expect, look in the app menus in the menu bar to see the correct shortcuts. You can also use the keyboard viewer to see your current keyboard layout, known as an input source. See Mac keyboard shortcuts.
