Double click on the Symbol button in the object type palette in the Copyist Tools window to open the symbol palettes. Click on the Notes palette. The Notes symbols palette will open, showing you all of Copyist's noteheads.
Select the note head you want by clicking on it. The note head you choose appears on the Symbol button.
Now enter the note head symbol on your page. Do this clicking and holding down the left mouse button. The note head will appear at the mouse cursor. As you continue to hold down the left mouse button, you can move the mouse and the note head will follow, until you have positioned it where you want it on the page. When the note head is positioned where you want it, lift the left mouse button and the note head will be placed onto the page.
You can also enter note heads at the cursor position using keyboard commands. For example, a closed black note head is entered by pressing b, and a half note head is entered by pressing h.
You can move or edit the note head after you have entered it, by double clicking on the note head and selecting one of the edit operations from the edit menu that appears.
