Another chord exercise. The exercise is not yet finished, nor is the documentation.
On the top the the config page there is a frame labeled Lesson file, that selects what lessonfile to use. This frame is the same on all exercises that use lessonfiles. There are two combo boxes. The one on the let you select what collection of lession files to use. The collection 'solfege' contains the files distributed with the program. The 'user' collection is files created by you, by default located in $HOME/lesson-files. It is possible to define other collecitons by editing $HOME/.solfegerc1.9.
