Macros are fabulous! Any time you're going to edit multiple lines in the same way, bam! For instance, you've got a create table script, and want to turn the column defs into some code or type definitions. For me, macros are quicker than getting a regex right.

Or perhaps you're cleaning up a file, and there's a few common changes. Pop each into a macro and go to town. The low friction aspect makes them more common than the name might sound.
