\once \hide Notehead which doesn't work, it has to be NoteHead. You can insert this syntax using the command: Command: Insert Lilypond Insert or edit a directive in the LilyPond music typesetting language. This can be used for extra spacing, transposing or almost anything. See LilyPond documentation for ideas. Location: Object Menu ▶ Directives Internal Name: InsertStandaloneDirective To have it readily available you could double click on the directive and start the Object Editor and choose "Create Button for Clone" which would give you a button in a palette for inserting it in future. However it would be much better if it were *not* a standalone directive but rather attached to the note. To do that use the command: Command: Attach/Edit LilyPond to Note Inserts LilyPond syntax you give before and after the note at the cursor height, also allows editing/deleting. Location: Object Menu ▶ Notes/Rests ▶ Directives Internal Name: InsertNoteDirective and put \once \hide Notehead before the note. Then as before you can create a button to insert this syntax. Which brings us to the starting point, the command Command: (Print) Hide Object Hides the object at cursor position with a lilypond directive. Currently only Notes and the three Signatures. No rests! Location: Object Menu ▶ Directives ▶ Typesetter Internal Name: Hide This command was not doing what its Help says it does. Looking at the history of it in the repository it seems something is corrupted. I've restored it to what I suspect was the original script. It now does do what it says (although hiding a note is limited to hiding the notehead and not the stem). This was clearly an unfinished project, to create a command that would hide any type of LilyPond object. As such I think it was misguided, not least because the directive created is closely linked to the object that follows it and can't be moved elsewhere with any reliable result. I think it should be retired. HTH Richard > I found the command under 'Adding timing marks to long glissandi'. > > I've been applying small changes to an example that I previously > submitted.
