What Is the Control Key?
The Control key is a key you hold down while you press another key, so that the two together do a task. On a Windows computer, holding Control and pressing C copies what is highlighted. Pressing Control on its own does nothing that you can see.
What it looks like
It is in the bottom row of the keyboard, at or near the left corner. Many Windows keyboards have a second one at the right end of the bottom row.
On Windows and on a Mac
On a Windows keyboard it is marked Ctrl. On a Mac keyboard it is marked control or ⌃, a small mark like an upside-down V. On a Mac, copying uses the Command key instead, and holding Control while you click opens the same menu as a right-click.
