How can i rotate and tilt a space ship on the same button press?,How can i make a spaceship both rotate and tilt on button press?

I am fairly new to unity. I have a spaceship model that I want to rotate and tilt to the left when I press the key 'A', and rotate and tilt right when I press the key 'D'. I want the tilt to go back to zero or the original state of the ship when I release the button. I got down the rotate working just fine I just am lost on how to make the same button tilt the spaceship as well. any help would be appreciated.
