Keyboard Mapping
Click on Midi Mapping from the Settings in the top left (※Keyboard is also treated as MIDI mapping)
UI elements that can be keyboard mapped turn blue, and a window called UIInspector is displayed.
UIInspector shows the keys currently mapped to the selected UI element.
When you click on a UI element, it turns red.
In this state, if you input the keyboard key you want to map, that UI element and keyboard will be linked.
Some modules in NodeEditor can also be keyboard mapped.
