Sniper zoom - how to activate?

[Superfan]

Hallo,

after a long time I reanimated one of my most favorite games. :-))

I´m stuck now at the point, where I have to activate the zoom function of the sniper rifle.
Within the settings I coudn't find the related item.

Could someone help me out here? Thanks!

It's the Alternate Attack in the menu. Default is the mouse3 button and M
