keyboard shortcuts
Keyboard shortcuts are keys or a combination of keys you press to quickly perform tasks on your computer. For most shortcuts, you press combinations of two or more keys, or you press a key while clicking, tapping, or dragging. For example, to copy some selected text, you can press Command-C, or you can press Option while dragging the item.
To see a list of shortcuts, open the menus on the left side of the menu bar. If a menu option has a shortcut, it’s listed next to the option.
For information about the symbols representing modifier keys in shortcuts, see the Apple Support article Mac keyboard shortcuts.
