"If the UI Mod was installed correctly, you should now see a small xbox controller icon in the lower right-hand corner. Left-clicking this icon will bring up the Combo Editor. Note that technical limitations prevent using the controller from being used to enter these combos, so don't bother trying. Using the keyboard, you can begin building your combo library. Valid combos are up to 5 key/modifier pairs...Hint: don't try to make them all up front, just play for a bit and whenever you're like "shit, I need to do this fast", go make a combo"
