Auxiliary Low C(sharp)
The touch is added alongside the low B natural key just above the low C touch. It enables the left thumb to operate the low C(sharp) key. This can be used to play a low C(sharp)/D(sharp) trill. The Auxiliary Low C(sharp) Spatula is simply a touch added to the middle of the long hinge for the low C(sharp) key. The action of this key is inferior to that of the Auxiliary Low C(sharp) Mechanism, although its use is identical.
