Commanders edition, p. 76-91 is just a list of every special ability and what it does. After that are more pages with a list of every pilot special ability and then formation ability.
It can be a bit ponderous looking up the mech abilities, since they're split into base and optional abilities, without much way to know ahead which list an ability is on. Plus sometimes the keywords differ enough from the actual ability name, so actually finding it can be difficult.
There's is a charger cheat sheet out on the net somewhere, but it's now missing from the site I had seen it on previously.
