key binding for Toggle Audio Click

There doesn’t seem to be an entry for Toggle Audio Click in Ardour.rc. Is there a reference page somewhere that lists all possible key bindings? I want to make F4 toggle the audio click on and off.

there is no keybinding for it.

in current GTK(2), something has be in a menu for it to have a keybinding. click on/off is not in a menu.

please file this as a feature request in the Issue Tracker.
