How do you issue an attack command?(pc)

Borderlands 3 FL4K the Beastmaster
#1

This is a bit embarassing, but I’ve gone 11 levels without learning what button activates an attack command. What button is it?

#2

I haven’t played fl4k yet but from what i’ve heard you hold the action skill button. Hope that works D: happy looting!

Thanks!
