contains a list of a dispatchable settings
each setting contains :
category : one of
none : a direct event call
arg : a event that expects a gesture object or an argument
absolutenumber : event that sets a number
incrementalnumber : event that increments a number & accepts a gesture object
string : event with a list of arguments to chose from
event : what to call .
title : for use in ui .
section : under which menu to display ( currently : device , filemanager , rolling , paging )
and optionally
min / max : for number
default
args : allowed values for string .
toggle : display name for args
separator : put a separator after in the menu list
