Arne,That was an elegant use of the key board, and I concur entirely.
I would add to the post about the "Tuning Key" or "Tuning Wrench" as they're called in the States (important only for word searches) that you should spend the extra couple of bucks and get a "T handle" tuning wrench as they are much easier to twist the pegs in the exact position for correct pitch, as opposed to the standard "one lug" wrench.
