Bumblebee provides fuzzy matching buffer commands: :B, :Sb, and :Vb.
Bumblebee "overrides" Vim's native :b and :sb commands by using a smart
abbreviation that expands to :B and :Sb respectively. :vb is also
expanded to :Vb for consistency.
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/PeterRincker/vim-bumblebee.git
Once help tags have been generated, you can view the manual with
:help bumblebee.
