I have an easier time searching and finding in Unix info and emacs-info, and I'm no unix expert. I regularly browse the "See Also" function-list at the bottom, but in this case the word 'Through' had looked unlikely in my wrong estimation. When you're traversing a massive graph, you can't click every hyperlink link.
Has anyone made an ordered tree (i.e., a structure like a conventional table of contents) of all the tutorials? An ordered table-of-contents to the tutorials that could be browsed from beginning to end? Books provide one, and Unix info does too, and I guess it helps me to associate various topics with various areas in the physical appearance of the ordered TOC as I'm getting familiar with a technical book. Getting to know a 2D image with a peculiar shape might be easier than navigating a graph with who knows what topology.
Unix info allows me to navigate without taking my hands off the keyboard, more efficient and less stressful because my mouse stresses me.
