Why is it that hammer noobs always try to hack their maps in the most complicated ways? :heee:
1.) if you want to assign sounds to the player's (real-world) keyboard keys, I'm sorry, that's not possible without coding your own mod.
2.) if you want to have ingame-keys (func_buttons for a number lock a la Doom3) that'll be super-complicate, too, and would make it necessary for you to explain in detail what it is you want to do before we could help.
Good luck with your mapping :wink:
Why snark works.
