+1.  In the meantime, the minority of users who want an abbreviation can define 
one, right?

I agree that lots of duplication is something that should be avoided, but so is 
the conflation of style and meaning.  A lyric hyphen separates syllables; this 
arrow thing means something more.

It reminds me of the abuse of rehearsal marks for several categories of 
instructions.  You build up a body of work full expedient little tricks; then 
one day you want to move all your "D.C." marks, but not your rehearsal marks, 
to the other side of the staff in certain scores; and then you learn what a 
mess it really was from the beginning.

I haven't looked at the code, but maybe factoring out shared functions would 
help reduce duplication.
