Back it out — vim

Try it on a real buffer

The return line is indented too far. Move onto it (j) and dedent it one level with <<.

def total():
    return 42

Canonical solution: j << · target: 3 keystrokes — the fewest that solve it (every keypress counts).

Why it works

<< removes one shiftwidth of indentation; >> adds one. If a line is buried under too much whitespace, stack them (2<<) or just repeat with the dot command.
