 If you are on Windows you may find the command prompt pops up briefly every time vim-gitgutter runs.  You can avoid this by installing both [vim-misc](https://github.com/xolox/vim-misc) and [vim-shell](https://github.com/xolox/vim-shell).  If you have those two plugins but don't want vim-gitgutter to use them, you can opt out with `let g:gitgutter_avoid_cmd_prompt_on_windows = 0` in your `~/.vimrc`.

+You can jump between hunks with `[c` and `]c`.  You can preview, stage, and revert hunks with `<leader>hp`, `<leader>hs`, and `<leader>hr` respectively.
