It seems that this requires a C++ extension.
Namely, \key only generates a KeyChangeEvent, so Scheme macros cannot
access the current key signature. And \key is a C++ primitive, so
replacing it with a Scheme function will not work.

A nice way to make this work would then be to make the current key
signature available to Scheme functions and make a generic function
such as
     b \ornament #'prall { cis }
and then shortcuts (pralltoo foo) => (ornament #'prall foo) etc.

(By the way, couldn't this lead to mainstreaming articulate.ly ?)
