Question: yaw control in jetborne flight

[Jinker]

Hey folks, I've seen several air display videos of the Harrier in which the pilot turns the aircraft in yaw direction while hovering... is this done by differential nozzle outputs? And through which control in the cockpit?

There are basically air jets that are at the wingtips, the nose and on the stinger behind the tail, these are used for Pitch, Roll and Yaw while hovering. I believe they are activated under a certain airspeed

[Rammit]

Iirc they are activated by a butterfly valve linked to the nozzle lever, the more nozzle deflection the more air flowing to the reaction jets

To answer the original question regarding how they're controlled - the pilot uses stick and rudder bar to control them.
