Here's a basic tip that works for both Acrobat and Reader. In a long document, if you need to jump to a specific page (say it's listed in the table of contents, or referenced in the text) just click once in the page number box at the bottom of the window. (It's the box that tells you which page you are currently viewing, and says something like "1 of 456.") When you click once, it highlights the numbers -- just enter the page number you want to go to, and hit enter. It jumps you to the page.
If you can't bear to take your fingers off the keyboard, Shift + control + N will pull up the "go to" box, where you do exactly the same thing.
