Can someone please tell me or provide a link to the keys for the emulator? I can't find the documentation, if there is any.
EDIT: Appearently someone make a key map, but the server is down. (http://florisfredrikze.nl/emumap2/index.html)

I think some documentation should be in the first post. It was hard enough for me to find the installation instructions hidden inside this 16-page thread! I tried opening calcemu_cx.tns without properly renaming the rom because I had no documentation, and it froze my nspire cx causing me to reset and corrupt entire device. I had to wipe the whole thing.
