Consider the crotchet rest in this bar from JSB WTC I Fuga IV:
Here’s my Dorico setting:
Most Urtext editions do put the rest snug up againsr the opening minim inside the staff. Using Engrave Mode I do not seem to be able to move the rest to the right of the minim. The rest does not seem to have a handle. What to do?
What I did was to set the crotchet rest (using force duration) to be the 2nd and 3rd quavers’ worth of a quaver triplet (hide the “3” and the bracket, and remove the quaver rest at the start), and then fiddle around a bit with note spacing in Engrave mode.
I don’t know either where the symbol originated. It catched my eye on an edition of the Art of fugue. At first I didn’t even notice that it represents BACH.
