Double click on the Symbol button in the object type palette in the Copyist Tools window to open the symbol palettes. Click on the Adjust palette. The adjustable symbols palette will open, showing you all of Copyist's adjustable symbols. The symbol at the bottom left of the miscellaneous symbols palette is the chord symbol. Select the chord symbol. The chord symbol now appears on the Symbol button.
Select the pencil tool from the toolbar and click the left mouse button where you want to enter the chord symbol to appear. When you enter a chord symbol, the Chord Name dialog appears for you to build the chord you want.
Select the root of the chord in the box at the left of the dialog. The root can have a sharp, a flat or neither after it, depending on whether you select n, # or b beside the name for the root note.
If your bass note isn't the root, you can indicate this. Check the Bass box and then choose the note you want for the bass. The bass can have a sharp, a flat or neither after it, depending on whether you select n, # or b beside the name for the bass note.
Type in the type of chord you want in the Type box. If you want to type in a flat symbol, type B. If you want to type in a sharp symbol, type #.
The Preview box will show you what your chord will look like. Note that numbers and accidentals appear in superscript.
