As far as I can tell, TheWiseFool isn't asking how to work Lum's machine, but the coloured dials on the level BELOW lum's machine. Yes you do get the key from working the dials. IIRC you don't have to press them in any particular order, you have to use the coloured globes you get when you press them with the coloured containers to get the key.
Illumina, I remember from using the machine that you can use it to get all your stats increased, however you can't increase them more than once. There's also IIRC a combination to get some experience. Unexpected things happen when you put in combinations that aren't on the notes, not because you've used it too many times [img]smile.gif[/img]
