And that's why KeyFinder is such a gem.
The Art Director's Toolkit would seem to be an application for a price (although I didn't actually go to the App Store to check it out – like everything on Apple's site, it takes forever to load [remember I'm on dial-up]). So that's a non-starter. I had the impression in a couple of articles that it was part of OS X.
I don't know if it makes a difference to you, but it's also available as a widget:
Apple - Downloads - Dashboard Widgets - Art Directors Toolkit Widget
