I wasnt happy with the default Rift Logitech G13 profile, so I modified it to what I wanted. My plan is ultimately to have M1 be a non-pet class and M2 before pet class characters. I dont have a character that is a pet class yet, so all I have modified is the M1 key. I usually put the jump action on my extra mouse button, but with Rift, I put shift and alt to give access to more quick toolbars. I updated my Rift keybinding to bind shift 1 to = to the second action bar and alt + 1 to = to the third action bar. Below is the keyboard layout for M1, as well as my mouse layout.
