The middle line should be indented under the if. Move onto it (j) and indent it one level with >>.
if ready: launch() done()
Canonical solution: j >> · par: 3 keystrokes (vimgolf rules — every keypress counts).
>> indents the current line, << dedents it. Give them a count (3>>) or a motion (>j) to hit several lines at once. The shift width follows your shiftwidth setting.
Reading about keystrokes doesn't build keystrokes. Try this in a real vim buffer right now — the “One step in” mission takes about a minute.
