I think this might be a duplicate but I can't figure out how to run this:

(man emacs)[cursor] [C-x][C-e]

Error I get back:

Debugger entered--Lisp error: (void-variable gpg)
  (man gpg)
  eval((man gpg) nil)
  elisp--eval-last-sexp(nil)
  eval-last-sexp(nil)
  funcall-interactively(eval-last-sexp nil)
  call-interactively(eval-last-sexp nil nil)
  command-execute(eval-last-sexp)

I'm trying to put a lisp expression in a file to open the man page in Emacs. So I can save an expression like this in my notes, and then open the man page in Emacs by running eval on the line.

I thonght it might be (man 'emacs), but It didn't work.

Try using any of the following examples, with double quotes around the MAN-ARGS:

(man "emacs")

or

(man "gpg")

or

(man "chmod(2)")

I don't have the gpg manual installed, but the other two examples do generate a manual buffer ...
