Come installare[modifica]

Se avete il monobook ufficiale[modifica]

Inserite nel vostro monobook il codice qed alla variabile toLoad

Se non avete il monobook ufficiale[modifica]

Inserite nel vostro monobook la seguente riga: 

document.writeln('<script type="text/javascript" src="/w/index.php?title=Wikiversità:Monobook.js/QuickEdit.js&action=raw&ctype=text/javascript&dontcountme=s"></script>');

Come configurarlo[modifica]

Si puo' (opzionalmente) configurare aggiungendo al monobook queste righe:

  • var qeEnabled = true; // Attivare lo Script? (valori "true/false")
  • var qeEnableSection0 = true; // Abilitare QuickEdit per la sezione 0 (introduzione)? (valori "true/false")
  • var qeEnableAccessKeys = true; // Attivare le chiavi di accesso (shortcut)? (valori "true/false")
  • var qeTextboxHeight = 20; // Altezza della finestra di edit
