Alt + F4 (PC)
The ‘Alt + F4’ keyboard shortcut is universally recognized across Windows operating systems as a command to close the currently active window or application. When you press ‘Alt’ and ‘F4’ together, the system sends a signal to the active application to terminate, allowing for a quick exit out of programs. This can be particularly useful when needing to quickly close a program, bypass unnecessary dialogs, or when an application becomes unresponsive. In addition to its primary function, if no applications are open, using this shortcut can bring up the shutdown options for the computer. Its widespread use and efficiency make ‘Alt + F4’ a valuable shortcut for managing open applications and controlling your workspace.
