The following function (probably poor): (defun increment-string (inc) "Find the next number in the current buffer and increment it leaveing point at the beginning of the number" (interactive "p") (let (beg end) (skip-chars-forward "^[0-9]") (setq beg (point)) (skip-chars-forward "[0-9]") (setq end (point)) (insert (int-to-string (+ inc (string-to-int (buffer-substring beg end))))) (goto-char beg) (delete-region beg end))) Allows you to write keyboard macros that trivialize this sort of editing. The ability to count and do relative numeric edits is my test to anybody that trys to espouse any other editor.
