Let’s assume you’re working in Windows and you’re looking to bring up the Arrange Icons By menu by right-clicking the mouse. You click and click and nothing happens. The application menu bar is no help, as all it provides is the option to send the CTRL-ALT-DEL keys to activate the Task Manager menu. You try various key combinations like Command-click or Option-click to no avail. Finally, your fingers ‘accidentally’ click the Control and Shift keys simultaneously and something miraculous happens: the context-sensitive drop down menu appears onscreen!
