Pull Knife: 1
Shoot: Left Mouse

so pretty much the regular, but with a few minor adjustments that i like =D (and because my keyboard's aren't the best... they are split into sub category's, and it makes it so i can only use 2 keys in any given category at one time... (i.e) i cant hold down W+E+Space at the same time... hence Shift being my main sprint, so i can still effectively power jump/power slide.. (although i did get to a point where i could power jump and slid despite only being able to use 2 keys at a time, and before i switched it from the default!) but E is also sprint, just in case iv been using my bros comp for to long and get used to it his way....)
and that's the end of my little rant on control configuration ! =D
