The Wrench is a tool in Refined Storage that has 3 modes.
To toggle the mode, right click with the item in hand in the air.
This mode will rotate any block. Use SHIFT + right click to rotate.
This mode will save configurations of Refined Storage machines to the wrench, and said configuration can be copied over to other machines as well.
Use SHIFT + right click on the machine to save the configuration, and use SHIFT + right click again on another machine (of the same type) to write the configuration.
To clear the configuration, switch to rotation mode.
This mode will drop the machine being right clicked on and will keep the configuration stored.
