How do you change HUD?

[Nitrofish]

I don't know if you call it HUD or what but whatever has the attack and stop button. Please someone tell me how to change the way it looks.

Change the icon of the attack and stop button?
Go the Scenario----> Game Interface.

I just recently learned how to do this and like GangSpear said it's under Advanced/ Game Interface. It should be listed as Icon - Command - (action), just be sure to click the little check box at the top left to use custom game interface.
