get most all my problems solved now, but I despair of really understanding
it, I tend to use trial and error.

Minimally, section 6.9 Quoting in the zsh info explains the three types of
quotes (backticks look like quotes but are really a substitution).

Then you need 14.3 Parameter Expansion and 14.4 Command Substitution to
explain what happens inside double quotes.  14.3.2 Rules and 14.3.3
Examples may be the most helpful.
