Use the property-cycle command. For example, to cycle /foo/bar between -1 and 0 you could use this: <button n="5"> <repeatable>false</repeatable> <binding> <command>property-cycle</command> <property>/foo/bar</property> <value>0</value> <value>-1</value> </binding> </button> You can have as many values as you want. If the current value of the property does not appear in the list, the command causes it to start over again. Make sure you don't include any duplicate values in the cycle.
