I’ve just added a new article annotating all the controls on the v8 Inspector: see here.
The content is covered (and cross-referenced) more thoroughly in the relevant part of aTbRef. However, here the information is in a single long form article which may make it earlier for learners (and those wishing to print it out to paper or PDF).
The above article is also added to the listing on my page of Clarify† articles.
† Clarify: this is just the name of the (now sadly discontinued) tool used to make the article.
