Toggle Interaction

Levers don't just switch redstone, they also let you switch interaction modifiers on slimestaffs from activating on using the staff to activating on attacking with the staff.

Never heard of a slimestaff? You will have to read the book by that nerd Melvin.

Untoggle Interaction

Its always possible to switch the modifier back after toggling it of course. Takes two levers, because you flipped it twice!
