Am playing on a Mac--during gameplay, I must have hit some weird key because I got a window saying something "enter a number" which I ignored, then realized I had somehow turned off the game buttons----ie, keys like G L T (get look talk) are not working anymore. In the text it said DEBUG KEY SET FLAG. What did I do??? How can I fix this?? Am I doomed??

I cannot figure it out and there's no mention of it in the walkthroughs! Apparently I have to get thru this before hitting the tiles leading to portal. HELP!!!
