Editing Pedal keyboard (section)

===Controls===

In some organs, a wooden panel called a "kickboard" or "kneeboard" is installed above the pedalboard, between the pedals and the lowest manual keyboard. Expression pedals, coupler controls and toe studs (to activate stops or stop combinations) may be located on or set into the kickboard. Expression pedals are used to open and close shades or shutters that enclose the pipes of a given division. Combination pistons are used to make rapid stop changes from the console on organs with electric stop action. Toe studs are pistons that can be operated by the feet, which change either the pedal stops or the entire organ.

In some organs, a "pedalboard check" mechanism serves as a safety catch, to shut off the pedalboard keys. The mechanism prevents accidental foot contact with the pedalboard from sounding notes in a section written only for the upper manuals.
