"Reveal" seems to be an alternate action to "open" – except it just opens some random thing that I have no control over. For example, "revealing" a ruby file in the Finder opens Path Finder (the third party Finder replacement).
So, what's it supposed to do? Can I have any control over how it functions?
I'm on Mountain Lion, but I think this is a long-standing action.
You may want to try Services Manager.app:
Download the application and put it into your /Applications folder (or any other convenient place). After you started it you can configure each service to appear in the Services menu (by enabling it in the Active column), in the Context Menu (by enabling it in the Context Menu) or in both.
Your wife has excellent taste in input devices. I use the same trackball daily, and if I can't also find a solid Lion solution, I'll be heartbroken (not to mention much less productive).
Kensington shipped four models of this type. The Expert and Turbo versions had slightly different coloring, and each came in wired and wireless versions.
According to Kensington's drivers page, TrackballWorks™ 1.1 for Mac was released on Oct 19, 2011.
[Note: yes, that's TrackballWorks, not MouseWorks—the latter was last updated in 2009.]
The Installation/Notes file says:
Requirements:
Apple OSX 10.5.6 Leopard
Apple OSX 10.6.x Snow Leopard
Apple OSX 10.7.x LionDescription: Enables trackball customization: button functions, pointer speed and acceleration, and scrolling speed and direction.
Languages: English
Installation: Save the DMG file to your desktop and double-click on it. Click on the installer package icon when it appears. Follow the on-screen instructions to install the software.
I haven't been able to get it to work, and I'm not the only one.

TrackballWorks - Supported Kensington Devices
Which Kensington trackball models are compatible with the software application TrackballWorks?
Kensington TrackballWorks is compatible with SlimBlade TrackBall model K72327, Expert Mouse model K64325, Orbit Trackball w/Scroll Ring model 72337, and Orbit Optical Trackball K64327.
Note that all the supported models have numbers greater than K642nn.
There are third-party mouse drivers. Some people have switched over to using USB Overdrive. I'm currently trying out SteerMouse, which makes the trackball work, but only has limited button support.
Neither focuses on supporting Kensington devices, or trackballs in general, which makes things problematic.

This is a Pathfinder feature that's designed to bring up the contents of your current Finder window in Pathfinder. There's no documentation for Pathfinder, so you'd have to check with their support team to see if it could do something different.
