I've tried a lot of different ways of coding this but I'm stuck.

c_rotate(me,vector((key_q-key_e)*10*time,my_angle.tilt-my.tilt,my_angle.roll-my.roll),glide);

instead of key_q-key_e I would like joy_force.x < 0-joy_force.x > 0

c_rotate(me,vector((joy_force.x < 0-joy_force.x > 0))*10*time,my_angle.tilt-my.tilt,my_angle.roll-my.roll),glide); This example is the wrong method
