As the title suggests, please make it so that the players can simply activate dragonriding from normal flight by simply clicking the already existing dragonriding skills, and visa versa.
So from ground level; space bar lifts players into normal flight while lift off would immediately put them into dragonriding.
While in normal flight and above ground; skyward ascent and / or whirling surge would activate dragonriding.
And to exit dragonriding; players use aerial halt and return to normal flight.
