I've used LaunchBar for years. It's astonishing. I'm disappointed they never did a Windows version; even today the Windows imitators I've seen are worthless fakes.
Despite all my use, I've never tweaked the default configuration, nor explored all the advanced options. In part this is because my wife has first dibs on the iMac, and I make do with a pathetic XP box (sniff).
Today though, I became fed up with a longstanding annoynace. I want to use Launchbar to quickly navigate to folders, but the default setup indexes file names that clutter my search results. I prefer other methods to find files (Spotlight for example), LaunchBar works as my app launcher.
It turns out that it's only a moment's work to reconfigure Launchbar to ignore files and only index folders. Nirvana! I index applications, folders, and the address book -- nothing else. Works great.
I'm even experiencing with indexing the folder structure of my XP box, and scheduling an index update each night. I have a hunch that will work exceedingly well. I really do need to get my hands on a new MacBook.
If you don't use Launchbar you should, and if you do use it, browse the excellent web site. There are capabilities you don't know about ...
