Type carefully because a mistake can take you to the wrong location or to nowhere at all. If you know you typed correctly, be aware that the Internet changes rapidly. Use the directories and search engines. In general:

• Check each character before pressing Enter/Return.
• Use no spaces with Internet addresses.
• Use no period at the end (there may be a slash [/]).
• Use lowercase unless you are told that the program is "case sensitive" or you are copying an obvious capital in an Internet address.
• Use the Shift key (not the Caps Lock key) for the upper symbol on the number or punctuation keys.
• Be careful to distinguish between the letter l and the number 1, the hyphen (
• ) and the underline (_ [which is above the hyphen]).
• The ~ symbol is the Spanish tilde, above the grave accent (`) at the top left of the keyboard.
• Slashes (//) are forward slashes, at the bottom right of the keyboard.
• The Break key is also called Pause; it's on the top right of the keyboard, above Page Up.
• On the Macintosh®, Ctrl is (white-Apple) and Alt is (black-Apple).
• Within Websites, you can click on "buttons" on the margins of the page you're looking at:
  • Back takes you to the previous page.
  • Forward takes you to the next page, but only after you're first moved backwards.
  • Reload gets the Website back on your screen.
  • Bookmark saves the address of the Website to your list (also called Favorites or Hotlist).
  • Home gets you to the home page of your server-your college, library, or online service.
  • History lists the sites already visited.
  • Stop interrupts downloading or the attempt to reach a site, necessary during a slowdown.
  • The X or square in the top right-hand corner of the screen (or top-left for Mac) allows you to exit quickly-usually returning you to your home page, but sometimes signing you off.
