+/**
+ * @brief Allows you to pass an FName into an event handler.
+ * 
+ * This modifier allows you to type an FName directly into an input mapping in
+ * the InputMappingContext editor, and have that FName passed through to an 
+ * enhanced input handler.
+ * 
+ * This modifier has an FName UPROPERTY which is editable in the InputMappingContext
+ * editor.  At runtime, it encodes the FName as an Axis3D.  In the event handler,
+ * the Axis3D can be decoded back into an FName using DecodeFNameFromAxis3D.
+ * 
+ * One use for this modifier is when you want to know exactly which
+ * keyboard key triggered an EnhancedInput event.  You can put the key's FName
+ * into the InputMappingContext, and it will get passed through to the event
+ * handler.
