All keymaps are stored as their own attributes, and it works well for providing static keys and combo actions. An Xbox blog post says you can get four shortcuts if you assign actions to keyboard keys, something that wouldn’t be possible without the latest feature. This convenience is tied to the paddles of the Xbox Elite Wireless Controller Series 2 and the X1/X2 inputs on the Xbox Adaptive Controller.
Remember that a control key can be mapped to only one control key. So, you can put the action key on the whole list “Ctrl + Shift + C”, but trying to add a modifier to access the list like “Ctrl + Alt + W + E” will not work. Another thing to keep in mind is that the controller must be connected via a cable, or it must be connected to the Xbox Wireless Adapter during setup. Keyboard typing on the Bluetooth wireless bridge is prohibited.
