+The defaults in *Propriétés du folio* (*Folio properties*): what wires drawn
+later on the folio start from, and the folio-wide option
+*activer l'option un texte par potentiel*, named `onetextperfolio`
+(`"true"` / `"false"`). The other property names are the ones
+`setConductorProperty()` takes. A `folioIndex` of `-1` means the project's
+defaults, which each folio added later copies.
+
+```js
+for (var i = 0; i < qet.folioCount(); i++)
+    qet.setConductorDefault(i, "onetextperfolio", "true");   // one number per potential
+qet.setConductorDefault(-1, "onetextperfolio", "true");      // and on folios added later
+```
+
+Changing `onetextperfolio` shows or hides the wire numbers at once, so an
+export later in the same script draws them right. There is no undo for
+these, the same as in the dialogs.
