Hello, have you ever wanted to be able to jump or do another one function with two keys? For example: When you jump with 1. pressing spacebar and 2. mousewheelup. If someone thinks that this is unuseful tutorial, don't read it plz. I only want to help someone who have no idea. :) So, let's go. Probably you know that key bindings are listed in config.cfg in the config directory in gamedirectory xD First of all download this programe http://sourceforge.net/projects/notepad2/. Install it or extract... Run notepad and open your wanted config.cfg, for example if you want config.cfg from cs:source go to: Valve\steam\steamapps\youraccountname\counter-strike source\cstrike\cfg\config.cfg. Now i will show you how to bind two keys for jump and tw keys for crouch. Jumpers use for jump mousewheelup or down or space, and for duck mousewheelup or down or ctrl, but you can't bind the same key for jump and duck, it's logical. So now... find the line: bind "space" "+jump" how you can see the name of jump function is +jump and key is binded to space, so now make a new line and type there bind "mwheelup" "+jump" it causes that you have jump binded to space and to mousewheelup. And then find bind "ctrl" "+duck", again you see that +duck is name of the function duck and is bidned to ctrl. Now make new line and type there: bind "mwheeldown" "+duck". Don't forget to save the config. That's all. Sorry for my english, hope it will be helpful. Bye
