Scripting Q

[EvilBaga]

I was wondering if there was a way to make a cfg that would only be implemented while a button is being held down.
For eg, I would like to have normally, mouse sensitivity 2.33, and while i press and hold down mouse button 2, the sensitivity to be 3.87.
This would be very useful for sniping, and for firefights, once one could get used to it.

bind mouse2 “+vstr lowsens highsens”
set lowsens “sensitivity 2.33”
set highsens “sensitivity 3.87”
