If you're facing an unresponsive application on your MacBook Air, such as Gmail, you can use a convenient keyboard shortcut to force quit the program. The key combination you need is Command (⌘) + Option (⌥) + Escape (⎋). When pressed simultaneously, this will open the "Force Quit Applications" window where you can select the non-responsive app and click on the "Force Quit" button to close it.

For additional methods, you can also choose to force quit from the Apple menu. Simply click the Apple logo in the top left corner of your screen, select "Force Quit," then pick the troublesome app from the list and click "Force Quit."
