Tip: Another way to show the value of a variable is: type the variable in a buffer, then Alt+x eval-last-sexp. Result is shown in Messages Buffer

Alt+x apropos-variable
Show variables that match PATTERN. Note: this does not show arbitrary elisp variables such as (setq xxx 3). Only those declared defvar, defconst, defcustom.
