How do you reset the Controls in Tomb Raider 3? I have messed up some of the key assigning's and they wont chance back.

If you go into the Tomb Raider 3 install folder (C:\Program Files (x86)\GOG.com\Tomb Raider 1 2 3\Tomb Raider 3) and delete the text file "config.txt", that will remove all of your TR3 settings, including your customised controls (you'll have to re-select your graphics options the next time you run the game, but the user keys will be set back to the default).

It worked :) Cheers!
