don't unzip, edit the file while it's still in the zip (said before i know) and make sure you open the right one. (config_preset_common.cfg.comp) go to the bottom, hit enter, add a new one (i gave an example above) and hit enter after you close each one, make sure theres quotes around the bind you want (bind "k" "plr_move_speed_normal 5000") for example. then save it winrar will ask if you want to update the file inside, hit yes. close the zip and then make it back to hfs and replace it. (vzipflip h fac...hfs) good luck ^^
