(1) In Windows, a shortcut is an icon that points to a program or data file. Shortcuts can be placed on the desktop or stored in other folders, and double clicking a shortcut is the same as double clicking the original file. However, deleting a shortcut does not remove the original file. In the Mac, a shortcut is called an "alias." See Win Shortcuts.
(2) In the Mac, a shortcut is a keyboard command that activates some function. For example, pressing F12 displays the Dashboard widgets. Keyboard shortcuts are configured in the Keyboard Preferences panel.
