"Show Options" link on your results page? Do a search for whatever interests you and try it (it's located right under the Google logo). This will add a left navigation bar with some very useful filtering options. Of note, you can narrow to a trendy real-time search buy clicking on "Latest" under "Any Time"; choose a date range,filter out the pages that you've seen, or haven't seen yet - how useful is that for finding that page that you googled last week but didn't save? The funny thing is that Google has an "Advanced Search" screen, which, of course, can do many things that this bar can't (such as searching for public domain media).
But if you're the slightest bit of a power user, or you work in an environment where users share mailbox folders or use Exchange's Public Folders, than keeping track of all of those folders can get a bit tedious.
That's what the Shortcut view is for. Buried below the Mail, Calendar and Task buttons, you can move it up to the visible button list by right-clicking on the bar area (in the lower-left hand corner of Outlook 2003 or 2007's screen) and choosing "Navigation Pane Options". Highlight "Shortcuts" and then click "Move up" enough times to get it in one of the first four positions. Click OK, then click on the "Shortcuts" bar. From here, you can add new shortcuts and, optionally, arrange them in shortcut groups. You can rename the shortcuts with more meaningful titles, so that, if, say, you're monitoring a norther user's inbox, you can give it their name instead of having two folders named "Inbox". One tip: to add shortcuts to a group, right-click on the group title and add from there.
