Moving to the start of a code line: Emacs

Question

I use emacs for development and very often need to move to the start of a line (C-a). However if the line is indented, I\'d like to move to the point at which code st

Answer 1

A favorite way for me to handle this is to have C-a toggle between the beginning of the line and the beginning of the code. You can do so with this function:

(defun beginning-of-line-or-indentation ()
  "move to beginning of line, or indentation"
  (interactive)
  (if (bolp)
      (back-to-indentation)
    (beginning-of-line)))

And add the appropriate binding to your favorite mode map:

(eval-after-load "cc-mode" 
     '(define-key c-mode-base-map (kbd "C-a") 'beginning-of-line-or-indentation))
