Non default (or just emacs) key printable map reference

Any suggestions on where to find or how to do this?

I saw a posting from 2008 asking the same question with no response.

Is it that hard to do?

If someone at Intellij can send me the data maybe I can try to make the map.

If it is in the open source code just point me at it and I'll see what I can do to make a crude table.

Thanks
