Useful page for SAP eLearning (LSO) transactions

One of the things I've had to do recently is translate transaction codes into the actual name of the transaction. Not much of a problem for the commonly used transaction (e.g. PA20, PA40, PPOME &c) but finding information on the web about LSO transactions, the learning/eLearning/training suite, has been very difficult. Finally I found this page which has all the ones I'm looking for. I found it Googling for LSO_RHABLAUF_OLD, what surprised me is that it didn't come up for the other transaction codes I'd been searching for earlier.
