Final answer:
The Com (mac) + 'D' command is used to quickly minimize all open windows and access the desktop on a Mac computer.
Step-by-step explanation:
The Com (mac) + 'D' command is used to quickly and conveniently minimize all open windows to access the desktop on a Mac computer.
To use this command, simply press and hold the Command key (⌘) on your Mac keyboard and then press the 'D' key. All open windows will be minimized, allowing you to easily view and access the files and icons on your desktop. To restore the windows, you can either click on the minimized windows in the Dock or use the Com (mac) + 'Option' + 'D' command.
This command is a handy shortcut for quickly organizing your workspace or accessing files and shortcuts on the desktop without having to manually minimize each window individually.
