How to make 'emacs' indent with tabs exactly how 'nano' does...?

Question

How can I configure ~/.emacs so that I indent how nano does by default?

• Uses a tab character instead of 5 spaces
• I can add as many tabs to a line as I please

Answer 1

I added the following to ~/.emacs:

(setq-default indent-tabs-mode t)
(setq backward-delete-char-untabify-method nil)
(setq indent-tabs-mode t)

(defun my-insert-tab-char ()
"Insert a tab char. (ASCII 9, \t)"
(interactive)
(insert "\t"))
(global-set-key (kbd "TAB") 'my-insert-tab-char) ; same as Ctrl+i
