And it takes less time than drinking a 33 cl 2.8% beer. Ba ba ba ba ba ba ba. Done. For configuration files absolutely unnecessary both keyboard macros and Elisp. Perhaps for huge batch data files, but then I'd use some shell processing tool to clean that up, rather. Here, I say "Elisp" as in Elisp to do the specific case. But Santa has a few helpers that works in general, and can be applied to many situations, e.g.: http://user.it.uu.se/~embe8573/emacs-init/align.el >> Learn to type really, really fast.

Doing Elisp also has errors (bugs) but 1) they are much easier to fix, and 2) the solution is transferable and transformable. Keyboard macros are poor-man's programming by definition. Will be inferior, always. And they don't lead anywhere. Elisp on the contrary leads to more Elisp, to the destruction of many young men's careers and so on. But what do you need a career for when you have Elisp? TEHO, of course. -- underground experts united http://user.it.uu.se/~embe8573
