I've never seen a standard mapping for them. They are pretty open to
interpretation so you may have a problem finding a consensus.

I'd bring up xevent or whatever and push/pull/poke/twist, take note
of what events it generates and do your own thing. Perhaps THAT would
become the standard. We have to start somewhere, your idea may be the
start of it.
