Slash Flagged Grace Notes Plug-in, Slash Flagged Grace Notes (Remove) Plug-in
How to get there
Choose Plug-ins > Note, Beam, and Rest Editing> Slash Flagged Grace Notes or Slash Flagged Grace Notes (Remove).
What it does
Use the Selection tool to select a region from which you wish to place slashes on all flagged grace notes (or remove slashes placed in Speedy Entry). This plug-in is equivalent to pressing ` (accent) in Speedy Entry to add or remove a slash from a flagged grace note.
This feature works best when the global setting for grace notes does not use slashes. See Document Options - Grace Notes.
