[SELECT ALL] Code:

alias sensitivitychange [
if (= (curweapon) 0) [sensitivity 2.6] [] //knife
if (= (curweapon) 1) [sensitivity 2.6] [] //pistol
if (= (curweapon) 2) [sensitivity 2.6] [] //shotgun
if (= (curweapon) 3) [sensitivity 1.8] [] //subgun
if (= (curweapon) 5) [sensitivity 2.2] [] //assault rifle
if (= (curweapon) 6) [sensitivity 2.6] [] //grenades
if (= (curweapon) 7) [sensitivity 2.2] [] //sniper rifle

Yes it is possible, to do it all you need to now enter is

[SELECT ALL] Code:

bind "MOUSE1" [attack; sensitivitychange]

Also you should change

[SELECT ALL] Code:

if (= (curweapon) 7) [sensitivity 2.2] [] //sniper rifle

To

[SELECT ALL] Code:

if (= (curweapon) 4) [sensitivity 2.2] [] //sniper rifle

The change is that the weapon is 4, not 7.
