How to Delete Icons
One of the easiest things you can do on your Mac or PC is to delete icons. You may periodically save icons to your desktop because you have saved a file or program that you want to easily find in the immediate future. Later, however, you may find that you no longer need the file. In these cases, you can delete the icons so they do not clutter up your desktop.
On a Windows PC or Mac desktop
Locate the icons you want to delete.
Left click on the icons while holding the "Ctrl" key. If using a Mac, hold the "Command" key.
Right-click your mouse and select "Delete."
From a Mac Dock
Locate the icon you want to delete.
Click and hold the left mouse key on the icon.
Drag the icon off of the dock and onto the desktop. A small digital poof of smoke will appear and the icon will disappear.
