Comment stuff out. Use \\\ to comment out a line (takes a count),
\\ to comment out the target of a motion (for example, \\ap to
comment out a paragraph), and \\ in visual mode to comment out the
selection. That's it.
Install repeat.vim to enable
repeating with . the line commenting map \\\.
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 less than 50 lines of code.
Oh, and it uncomments, too.
If you don't have a preferred installation method, I recommend installing pathogen.vim, and then simply copy and paste:
cd ~/.vim/bundle
git clone git://github.com/tpope/vim-commentary.git
Once help tags have been generated, you can view the manual with
:help commentary.
My favorite file type isn't supported!
Relax! You just have to adjust 'commentstring':
autocmd FileType apache set commentstring=#\ %s
