You can use something like this for esp on and off to turn the red squares (of where the enemy is) on and off.

bind i { esp.active toggle; esp_onoff }

But for the actual wall hack, you can do the same but last I tried, it was buggy on a toggle. It basically wouldn't turn back off. You turn on/off wallhack like this (if the code isn't still bugged):

bind z { vis.wallhack toggle; wall_onoff }

You can google famous CSGO players' configs. They're everywhere and very subjective.

I bind space (jump) so that when I jump, I duck, making it easier to get on to boxes in places like Dust2. I have f and v bound to flashbang and grenade to for quicker access. The last bit is the cross hair I use. I have all of this in autoexec.cfg

bind "space" "+jump;+duck;-duck"

bind "f" "use weapon_flashbang" 
bind "v" "use weapon_hegrenade" 

cl_crosshairalpha "255"
cl_crosshaircolor "5"
cl_crosshaircolor_b "255"
cl_crosshaircolor_r "255"
cl_crosshaircolor_g "0"
cl_crosshairdot "1"
cl_crosshairgap "0"
cl_crosshairsize "5"
cl_crosshairstyle "2"
cl_crosshairusealpha "1"
cl_crosshairthickness "1"
cl_fixedcrosshairgap "0"
cl_crosshair_outline "0"
cl_crosshair_outline_draw "0"

Easy to deal with, super fast and reliable. You won't be disappointed.
