LaGrange points

Is there anything in orbit at any of the LaGrange points? Just curious. How would one find a point like that in Celestia?

make a text search for "LaGrange" either using grep or using a windows own tool in the data files, and look for a keyword and take the name of the object, start celestia, hit "return" key, and enter the name... afterwards click on "G" (if it was selected) and you should move there ;)

There are several spacecraft at Earth-Sun L1 and L2, sun observation (SOHO and Genesis) and deep space observation (MAP). To my knowledge there are no natural bodies in the Earth-Sun or Earth-Moon Lagrange points, though I believe there are several asteroids about Jupiter's L4 and L5.

Some of the big asteroid data files on Bruckner's site include some of the asteroids known as Trojans, which orbit in two diffuse clouds surrounding the Sun-Jupiter L4 and L5 points. You can see the clouds clearly if you use one of these files and turn on name display.

Telesto & Calypso ( moons #10 & 11 of Saturn ) orbit in the LaGrange points of Tethys ( moon #9 of Saturn ). However while Tethys is in Celestia ... Telesto & Calypso are not.
This is a pity as it would be interesting to visualise these orbits.

Similarly , Dione & Helene share an orbit of Saturn with Helene in Dione's LaGrange point.

They are !

Have fun.
