Computer Concepts and Applications Practice Test

A keyboard shortcut is a key or combination of keys that provides quick access to a function within a program, letting you perform actions faster than navigating menus. For example, pressing Ctrl+C copies selected text, Ctrl+S saves the document, and Ctrl+Z undoes the last action. Shortcuts speed up workflows by triggering commands instantly. While function keys (like F5) are commonly used for shortcuts, the concept includes any key or combo that invokes a command, not just a single function key. An external device to unlock a PC isn’t a keyboard shortcut, and a mouse shortcut uses the mouse rather than the keyboard.
