How do I change indentation in Emacs?
Emacs normally uses both tabs and spaces to indent lines. If you prefer, all indentation can be made from spaces only. To request this, set indent-tabs-mode to nil . This is a per-buffer variable; altering the variable affects only the current buffer, but there is a default value which you can change as well.
