I'll plug our shortcut feature here as well...
If you have some sites that you go to a lot but don't want to type the whole url or find in bookmarks, you can add a shortcut to the bookmark. So, you could make "g" take you to "www.google.com" or "gm" take you to "www.gmail.com".
Even cooler, you can create search shortcuts so that (for example) to find all the pizza restaurants from
www.dexonline.com, all you have to type is "dex pizza".
