Comment stuff out. Use gcc to comment out a line (takes a count), gc to comment out the target of a motion (for example, gcap to comment out a paragraph), gc in visual mode to comment out the selection, and gc in operator pending mode to target a comment. You can also use it as a command, either with a range like :7,17Commentary, or as part of a :global invocation like with :g/TODO/Commentary. That's it. I wrote this because 5 years after Vim added support for mapping an operator, I still couldn't find a commenting plugin that leveraged that feature (I overlooked tcomment.vim). Striving for minimalism, it weighs in at under 100 lines of code.
