+ Pressing the Output button causes the Faderport to control
+ the fader, pan, mute and solo settings of the Master bus. If
+ your session does not contain a Master bus, it does nothing.
+ This is a toggle button - pressing it again returns Faderport
+ to controlling whichever track/bus was selected before the
+ first press of the Output button.

+ If your session uses Ardour's monitor section, you can use
+ Shift-Output to assign it to the Faderport in the same way
+ that Output assigns the Master bus. This is also a toggle
+ setting, so the second Shift-Output will return the Faderport
+ to controlling whichever track/bus was selected before.
+ </p>
+ <p>
+ If you press Shift-Output after a single press to Output
+ (i.e. control the Monitor Section while currently controlling
+ the Master bus) or vice versa (i.e. control the Master bus
+ while currently controlling the Monitor Section), the press
+ will be ignored. This avoids getting into a tricky situation
+ where it is no longer apparent what is being controlled and
+ what will happen if you try to change it.
