cool, thanks for the help

This question is in terms of HUD animation and more specifically, HUD crosshair animation.

I am wondering if a player being damaged is the only event that can trigger an animation within your HUD. It's the only event that I've seen after some light research and I kinda want to be able to use specific buttons to trigger animations.

Its a pretty straight forward question, however if this isn't the only event, I would appreciate it if someone could list any of the others.
