There are a few instances of unnecessarily keystrokes in this exercise. Moves to the start of the line for a command that will act on the whole line (0shift-D, 0shift-V, 0dd). The 0's aren't required for those. Also a few times it switches to command mode when the editor is already in command mode based on the last step. 0shift-V2j selects 3 lines, not two.
