Each time you make a change to your HTML source code using notepad.exe,
you must save the file before you can view your changes. After you save
the file, switch to the browser displaying your file and hit the Reload/Refresh
button to see the updated results. Holding down the [Shift] key while you click
on the Reload/Refresh button results in a more complete reload. The samples below
are typically what these buttons look like in your browser.
