Mac 101: system-wide thesaurus at the touch of a hotkey
As a Mac switcher, my Mac's built-in spelling and grammar checking has been a huge productivity boon for me. I'm someone who often gets stuck on a word, and since nothing's ever good enough for me, I've often wished that Leopard also included a built-in thesaurus. While that's not currently in the cards, there is an alternative. How many ways are there to say "Whoops?" Of course, Leopard does include a built-in thesaurus via Dictionary.app. See the continuation of this post for a screenshot. Thanks to everyone in the comments for keeping me honest.
If the Apple offering isn't to your liking, Nisus Thesaurus, a free app from Nisus Software, works as a standalone application and a system service. This means that it installs in the Services sub-menu of your Mac and is accessible from any program you use that is able to interact with the Services sub-menu. These applications include Mail, TextEdit, Safari, MacJournal, and countless others.
Once installed, using your new thesaurus is as simple as highlighting a word that you would like to look up, and pressing the Nisus Thesaurus Services sub-menu hotkey (Command -<). This will pop up the Nisus Thesaurus window with your word options only a click away. Select the word you would like to use as a replacement, press Command->, and voila; your new choice has replaced the original word.
Here's the Leopard version of the Oxford thesaurus in Dictionary.app for comparison:

Pretty nifty. I've always wondered: Quicksilver has a dictionary and thesaurus and it's what I use to look up words. Is it tied into OSX's dict and thes apps or using its own?

I use the dictionary dashboard widget for my thesaurus - it's built in and quick to access!

Leopard has both a build in dictionary and thesaurus built into the system.

Applications/Dictionary, click on the Thesaurus tab. No need for third-party software.

There's a thesaurus feature on the Dictionary widget in Dashboard! ^_^

Apple's built-in thesaurus even appears in the contextual menu. Highlight the word, select "Look up in Dictionary" and at the bottom left of the popup window you'll have the option to choose Thesaurus - fast and nifty.

PS - However, the automatic replace feature of the Nisus Thesaurus sounds neat, and it is not possible with Apple's built-in Thesaurus or Dictionary.

Mac OS X has a lot more in the cards than seen at first blush. As noted above, the builtin Dictionary has a Thesaurus, and is easy to summon by a variety of methods. One is the following:
Press Ctrl-Cmd-D with the mouse hovering over a word. A popup appears with the dictionary entry. You can then select the Thesaurus from a list at the bottom, or launch the full Dictionary.app (which takes a bit longer) with the "More" button.
While holding down the hotkeys, you can move the mouse around, with the popup following and updating.

Jason, my good man. Clearly your switch is not fully complete. OS X has a built in Oxford Thesaurus that is available wherever you can access the built in dictionary. Personally I prefer the contextual menu access as described by Mary above.

I will add that you can access the built in dictionary and thesaurus in many places in OS X, including contextual menus in all good apps (which excludes Word), the standalone Dictionary app, and the Apple widget. This, to many, is well known, but given that you apparently didn't know the Thesaurus existed, perhaps you don't. If you had opened the standalone Dictionary app, it hard to see how you missed the big interface button that says "Thesaurus".

Leopard does have a Thesauraus, Dictionary & the ability to use Wikipedia built right in to the system.
Check again.

You can even use spotlight to look up a word and access the dictionary/thesaurus that way.

Michael's comment (#8) sums up exactly what I was going to say, only better. No extra software is needed to look up words in dictionary or thesaurus. Note that Spotlight only looks up entries in Leopard.

You don't need to resort to the Dashboard, as Dictionary.app is sitting there right in the Applications folder. It's one of the things I keep in my Dock to avoid the distractions of Dashboard. The Leopard version also features Wikipedia. You can set it to look up 'Dictionary', 'Apple', 'Wikipedia' or 'All'.

Here's a way stupid question ... How do you trim the list of services from the "services" menu? I've got way more than I'll ever need, some are just plain dumb. If I could trim the list to a few that I need, it would be a lot more useful.

Are any of those keys mapped to some other functions? On a windows keyboard, I hold down the windows key, the left ctrl key, and the letter D then mouse over any word. Check your Dictionary app preferences? If it still doesn't work, perhaps you'd have to check with some forums. :)

Vopat: I think it doesn't work in all apps. Try it on Safari, TextEdit, etc
