"Modifier" keys include Control and Alt on Windows / Linux computers, Command and Option keys on a Mac, and Shift and (in some rare cases) Fn keys on any of the above platforms. These keys are nearly always pressed in combination with other keys to change their purpose - such as the classic "Control-C / Control-V" for copy and paste. However, all of these keys can potentially be used on their own if a program is designed to watch for them - most often, this is found in gaming, where keys like Control or Shift can be used for a specific command like firing a weapon or running.
