+/**
+ * The details of one preference which is constrained to be
+ * one of a small number of string values-- in other words,
+ * an enumeration.
+ *
+ * We could have done this other ways. One particularly attractive
+ * possibility would have been to represent the entire symbol table
+ * as a space-separated string literal in the list of symtabs, so
+ * the focus mode enums could have been represented simply by
+ * "click sloppy mouse". However, the simplicity gained would have
+ * been outweighed by the bugs caused when the ordering of the enum
+ * strings got out of sync with the actual enum statement. Also,
+ * there is existing library code to use this kind of symbol tables.
+ *
+ * Other things we might consider doing to clean this up in the
+ * future include:
+ *
+ * - most of the keys begin with the same prefix, and perhaps we
+ * could assume it if they don't start with a slash
+ *
+ * - there are several cases where a single identifier could be used
+ * to generate an entire entry, and perhaps this could be done
+ * with a macro. (This would reduce clarity, however, and is
+ * probably a bad thing.)
+ *
+ * - these types all begin with a gchar* (and contain a MetaPreference)
+ * and we can factor out the repeated code in the handlers by taking
+ * advantage of this using some kind of union arrangement.
