The Main Menu is at the top of the window, and provides the ability to make and restore from backups, open the help, register the program, and also all of the functionality that is available by right-clicking in the System Tree. You can also print from the main menu, as well as undo your actions. If you are currently viewing the Account Transactions Screen, you will also be able to use the "Import Data" menu item to import data from a file.
