For example, here's some emacs builtin variables. Try to find their value:
- user-init-file
- tab-width
- load-path
- find-file-hook
Another way to find the value of a variable is:
type the variable in a buffer, then
Alt+x
eval-last-sexp
Result is shown in Messages Buffer

apropos-variable - Show variables that match PATTERN.
Note: this does not show arbitrary elisp variables such as
