Ok so I have to be the one that UN-confuses people. That is not a script. All it is, is a different way of binding your keys and it does it all in one command instead of 4 or 5 commands. binding your "mwheelup" and/or "mwheeldown" to "jump" is perfectly legitimate. Also, just as a side note bhop servers most of the time even tell you to switch to your mwheelup or mwheeldown because it makes it easier to use then the space bar.
