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.

SAP HCM Standard roles

I've been trying to track down a list of SAP HCM standard Security and Authorisations roles. No luck so far.

I'm looking at test scenarios but the high level role specs I've been given so far (the roles are still being defined) just say things like "Z* version of SAP standard role for ...". Ideally I'm looking for role name, brief description and overview of what the role can do in SAP (i.e. transactions, infotypes and objects).

I've Googled but to no avail, just lots of job postings and people saying that if I go on their training course for X thousand Euro I'll know what the standard SAP HCM roles are. I did find a link that looked useful, it's to a sample chapter of "Authorizations in SAP ERP HCM", but unfortunately the sample chapter is not the chapter I need.

Gotta just keep on looking!
