Right-click the chord symbol you want to edit (or select the handle and press Enter) and choose Edit Chord Definition.
The Chord Definition dialog box appears.
Make the necessary changes in the Chord Definition
dialog box. To force the root or alternate bass to appear in lowercase,
click Lowercase to select it. If you want the root or alternate bass to
appear in uppercase, make sure that Lowercase is not selected.
Click OK to return to the document, where the
changes now appear.
