Raimon Grau over at puntoblogspot has a really useful quick tip on a couple of comment-dwim features that I didn’t know about. He shows how to
- Comment out a blank line.
- Remove an inline comment.
If you use comment-dwim (bound to 【Meta+;】), and you should, you should head over to puntoblogspot and take a look. It will take you less than a minute to read it but might save you some time and effort down the line.
