The Quick Controls Panel does not introduce new functionality, but helps triggering Themes fast and easy. This way you can test your soundtrack for certain in-game situations more conveniently. The Quick Controls Panel provides a collection of slots, where each slot can hold a single Theme along with an intensity value. Trigger the Theme by clicking the slot's trigger-button on the right, or by pressing the keyboard shortcut as shown on the left.
Remapping Keyboard Shortcuts
Right-Click on the displayed key on the left side of each slot to assign a new key. Make sure a soundtrack is loaded before right-clicking.
