WordPress’s mindless HTML stripping system messed my comment up. This should work.

I find move-buffer-file more useful with Ido, which is a relatively straightforward conversion.

(defun ido-move-buffer-file ()
  (interactive)
  (let* ((name (buffer-name))
	 (filename (buffer-file-name))
	 (dir (ido-read-directory-name "New directory: "))
	 (newname (concat dir name)))
    (if (not filename)
	(message "Buffer %s is not visiting a file." name)
      (progn
	(copy-file filename newname 1)
	(delete-file filename)
	(set-visited-file-name newname)
	(set-buffer-modified-p nil)
	t))))

M-x how-many RET \w+ RET

C-x h C-M-\

M-x rename-file RET RET RET

I don’t have an equivalent for the Amazon.com command, but you may want to look at Skeleton mode or Abbrev mode to accomplish those kinds of things.

Thanks, I was just thinking that I was going to write that Amazon function. I’d use format though…

The progn in ‘move-buffer-file’ is spurious. There’s an implicity progn in the else clause of an ‘if ‘ special form.

You can also replace the ‘if’ in the let* that binds dir by ‘when’.

Suggestions:
i) Put a link that using JS can display a markup help when entering comments.
ii) Put a preview button.

For counting words or other text elements there is also “M-x count-matches” command. For example, give it a regexp like \w+ or \S-+ and it will return the number of matches.
