Let's say you are using . You've staged some changes within the git index buffer using :Ge: and now you want to make a commit. From the git index buffer, you can hit cvc to pop open the commit message window in verbose mode. The verbose part means that all the staged changes are shown below as a reference for composing the commit message.
