•Most Windows keyboards contain two Enter keys, one in the main part of the keyboard and one in the numeric keypad. In FileMaker Pro Advanced, the Enter key in the main part of the keyboard behaves as the Return key.
•When the Tab key is set to go to the next field, you can still enter a tab character into a field by pressing Ctrl+Tab (Windows) or Option-Tab (macOS).
