Also something that helped me with making changes across the event handling code:
If you are using Visual Studio click on an event’s declaration. Then click Shift-F12 (Windows). This will show you all references (within your solution) to that event. Namely this is where you invoke it and where you are registering the listeners.
This addresses my question I initially posed here: Code Flow question - #7 by Cat_Hill It was closed so I couldn’t add to it.
