Add this developer script to userconfig.cfg
Use mwheeldown for LongJump
Use mwheelup + mwheeldown for CountJump
Use end for cl_sidespeed Value="300" and sv_airaccelerate value="100"

Cl_sidespeed give more pre and speed but the developer script give more.

Have fun.!

bind mwheeldown "+jump;wait;developer 1;fps_max 250"
bind mwheelup "+duck;wait;developer 1;fps_max 250"
bind end "cl_sidespeed 300;sv_airaccelerate 100"
