series of letters into commands for your computer. Used with the
control key, the letters normally won’t show up in the document
you’re typing. Some programs, by the way, may use the control key
and an =escape= key, which could be a way to get from one part of
the program to another. Or the escape key may take on functions
similar to the control key. In addition, there’s an =alternate= key
that you may also use to help boss your machine around.
