 *
 * This cannot be read off the names. The T-100 latches a function on
 * with one perforation and cancels it with a second, while the T-98
 * holds it for as long as one perforation lasts (Hagmann pp. 89 f. and
 * 100–103; Phillips p. 121), and Welte renamed two of the functions
 * between the scales: the red `SlowCrescendo` is the green `Crescendo`,
 * and the red's single `Forzando` valve answers to two green ones that
 * name the end they pull towards. So the correspondence is stated here
 * rather than derived, and only two types that operate one function can
 * stand for each other.
 *
 * `MotorOn`/`MotorOff`, `Rewind` and `ElectricCutOff` are left out on
 * purpose: the green scale has no word for any of them, its motor switch
 * being an automatic mercury contact (Skala-Rolle 98 §12) and its rewind
 * riding on the bass sforzando-piano line. A red command of those kinds
 * has no counterpart and stays a plain deletion.
