The Data Key/Value Editor allows global data keys and values to be defined. Key/value pairs defined in this editor will be applied to all songs. By using a global value, it is possible to define rarely-changing global text such as an organization name or other identifying information. The editor shows the text that must be entered in the song file to make use of the data key/value pair that has been defined.
See the ChordPro file format reference for more information about using data keys and values.
