==Come configurarlo==
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
