Just in case any of you go crazy and decide to be Technical Writers, let me impart this nugget of wisdom: when writing instructions, be aware that users PRESS keys on a keyboard and they CLICK buttons on the interface. These terms are NOT interchangeable.
Also, the SCREEN is the piece of hardware you use to see the application, but the application itself appears in a WINDOW. These terms are also NOT interchangeable.
Does no one remember what happens when you cross the streams? Bad things happen. BAD. BAD. THINGS.
