94 Learning the Basics Using the keyboard Keep liquids, including cleaning fluid, out of the computer's keyboard, speaker, and other openings. Never spray cleaner directly onto the computer and/or display. Never use harsh or caustic chemical products to clean the computer. Character keys Typing with the character keys is very much like typing on a typewriter, except that: ❖ The space bar creates a space character instead of just passing over an area of the page. ❖ The lowercase letter l (el) and the number 1 are not interchangeable. ❖ The uppercase letter O and the number 0 are not interchangeable. Ctrl, Fn, and Alt keys (Sample Illustration) Ctrl, Fn, and Alt keys The Ctrl, Fn, and Alt keys do different things depending on the program you are using. For more information, see your program documentation. Function keys The function keys (not to be confused with the Fn key) are the 12 keys at the top of the keyboard. (Sample Illustration) Function keys F1 through F12 are marked with icons and are called function keys because they execute programmed functions when pressed. For more information, see "Hot key functions" on page 179.
