Setting weapon groups?

[The.Outlaw.Star]

For the life of me I can not figure out how to set weapons groups. I recall being able to hit a button and switch groups, but what was it and How do i set them up?

when I hit shift+1 it just toggles that specific weapon on and off. this was the default weapon setting i had seen in UI.

if anyone has a command list please let me know. thank you.
