What should be added or changed?

• true/false config "reverse excavate key function" for lumberjack enchant
  mainly, lumberjack enchant only work while pressing excavate key. I hope a config setting make it reverse.
  while "reverse excavate key function = false", it's same as now.
  while "reverse excavate key function = true", lumberjack enchant only work while not pressing excavate key.

Why should this be done?

• Lumberjack enchant need for excavate function. why player hold "lumberjack axe" in his inventory? for cutting tree. many tree. but this enchant doesn't work while naturally cutting tree. it require press some key whenever cut every single tree.
  I understand there is some moment that want to stop lumberjack fuction for a while. I guess it's why excavate key exsist. so I request config setting instead delete it.

I apologize about my poor english. thx for reading.
