Is it a special character recognised by Minimserver? If so, i’ll need to be reminded of its significance.

It does indeed generate an index entry of Work, but I also struggle to understand the meaning of the backslash. In addition, I’m puzzled why I have to use Group when this has already been aliased to Work. My music files only contain the Work tag, not one called Group.
