Whenever a transaction is entered that refers to more than one currency, which includes using a currency other than the default currency of the account, the exchange rate editor pops up and allows you to enter an exchange rate to be used for that transaction. Initially, the current price available from the price database will be used as exchange rate. See Entering exchange rates for currencies for more information on how to provide exchange rates manually and obtain online price information.

Optionally, the exchange rate is saved in the price database once entered by the user.
