Can someone explain this syntax? eg Why is keymap the 3rd element in the char-table, and what does the "nil nil" before it signify? What is "#^^[3 0" ? What do the 3 and 0 mean here?
why does "(aref (nth 1 esc-map) 0)" return "mark-sexp"?
I couldn't find answers in the manuals for emacs or elisp, except maybe that "#^[ nil nil keymap" means character code 3 corresponds to a keymap in this char-table
