There is a way to use the LaserWriter fonts' diacritical marks, the curved
short-vowel symbol (shift-option-period) and the straight long-vowel symbol
(shift-option-comma). To put these symbols directly above a vowel as is done
with an accent or umlaut, you must create diacritical font characters using
Fontographer, from Altsys Corp, or some other LaserWriter font utility.
