title: Where is `git add` in Visual Studio Code?
body: <p>In Visual Studio Code, <code>Cmd-Shift-P</code> gives me the command palette. There are many Git commands listed in the palette, but the only result for "add" is "Add file to .gitignore". This is not what I want. I want the equivalent of <code>git add $CURRENT_FILE</code>. Such a command is provided, for example, by <a href="https://atom.io/packages/git-plus" rel="noreferrer">the git-plus extension to Atom</a>. What is its equivalent in Visual Studio Code?</p>
