If you need to change an exchange rate, either permanently or just for one transaction, you can do it when recording a transaction.
When entering a foreign currency transaction, click the exchange rate. The Currency window appears.
Change the exchange rate.
To change the currency's default exchange rate, click Edit and enter the new rate. This updates the rate in your currency list so it'll be used for this and all future transactions for this currency.
To change the exchange rate for this transaction only, select the Custom option and enter the rate.
