As an example,
if you click on a tree and get branches you get them until your full or the tree is empty,
bark on the other hand, you just get 1, then have to right click to open the options and click again.
I propose,
when you left click on an option/action the action is done once,
when you right click on an option/action the action is carried out until no longer possible, (no more branches/bark/wring neck/inventory full)
