On the altimeter in the default 737 is an orange triangle on the outer part of the altimeter. There is also a knob that turns it. This is also an orange triangle. Does anyone one know what this is?

it adjusts the pressure. Like when ATC tells you "Altimeter 29.92, You would turn the orange knob untill the numbers 2992 appear in the white boxes in the altimeter
As FEM states the "knob" on the left changes the pressure setting, the triangle moves the orange marker around the altimeter. "Why? This is used to set to remind you of an important passing height/altitude. On departure I set it to 1500ft AGL so when passing it reminds me of acceleration altitude (speed to 250kts flap retracted on schedule). On approach I set it to DA/DH acts as a backup or reminder that at x feet if not visual go around.
Thanks! The orange knob was the one that I wanted to know about.
