Shift is duck and ctrl is walk, CAPSLOCK is my mic button, ; buys me all grenades, ' buys me armor, helmet, full ammo, and a defuse kit; F1-F4 buys me pistols, F5-F8 buys me submachine guns, F9-F12 buys me rifles, ALT+F9-F12 buys me sniper rifles, [ and ] enable and disable dynamic crosshairs (respectively), - and = enable and disable cl_lc/cl_lw (respectively), p changes my crosshair color, / prompts me to change my name, kp_minus disables the net graph, kp_plus enables it with low settings, and kp_enter enables it with full settings.
Those are my right-handed binds... I'm working on a left-handed config too. So far, kp_home is reload, kp_pgup is quickswitch, KP keys 8456 are equivalent to WASD (respectively), kp_downarrow is use, kp_ins is jump, kp_plus is walk (walking is tricky), kp_enter is duck, kp_pgdn is scores, kp_end is mic, and kp_del is drop. I need binds for the weapons, too... I will probably make leftarrow slot1, downarrow slot2, rightarrow slot3, uparrow slot4, and the pgdn key slot5.
This's more of a CS customs topic... I always thought that that section would have attracted more scripters.
