Recipe overview displays all possible ways craft an object, whether crafting at a workbench, in a furnace, in a brewing stand, or with any added crafting method (for example, a smelting furnace in the RP2 mod). The back button ("BACKSPACE" by default) will display the previous recipe, and the Esc or inventory key will close the window. In the recipe window itself, left-clicking on an ingredient will open its recipe window, and right-clicking it will open the application window. Pressing the recipe ("R" default) or application ("U" default) button while hovering over an object will open the respective display mode. There are 2 functions in the recipe overview: Recipes and Application.
