Fireworks question (Macromedia, not explosives)

I remember working in Macromedia Fireworks and remember there was a button, or more accurately, series of buttons on the keyboard, where you could see what you had just made would look like on the Internet. I’m very computer literate, but for the love of me I cannot remember what those buttons were. Please help! Thanks.

Does anybody know?
