That is correct that the requirement to wait 500 ms would only be necessary if a double-tap action is defined. This does require reworking the code to "queue" the action to be fired and only fire it after the 500 ms is elapsed, so I'll have to make sure that this has no impact on the existing functionality. 

Long press is not an option because pedals do not have a "key up" type notification. They only send the key down and that's it, so there is no way for me to know how long they are held down or when they are released.
