To insert a new field into an existing database, at any moment of your choosing:

Command-L: Go to template Layout/mode/view.

Command-shift-D. Go to Definition mode/view. Choose a field type; name the field. Then click 'Done', unless it is a calculation field and you wish to construct an algorithm. This should be adequate in all versions of FileMaker from the first onwards. If 'add new field to template' was chosen in Preferences (supposing that the option existed) the new field is added to the layout view, and can be dragged wherever in the template you wish. If that preference does not exist, use the left panel from Layout mode to add a new field (by dragging), and you should be prompted to define it.

Command-B: Return to Browse view.
