Looking for debug tutorials

Can anyone suggest where best to find tutorials I guess a bit ‘beyond basics’?

for instance

  • there’s a list view… somewhere of all ops. Where is that and how best to make use of it?

  • how to tidy a network by collapsing sections, without breaking all the links?

  • this parm is referenced elsewhere in the network, how can I jump directly to that OP?

  • how to run (I guess?) the text port to watch for errors and what to do about them. What’s a cook dependency anyway?

With so much to choose from it’s challenging to know where to begin looking.

Any advice is appreciated
