Work with the AutoFill Editor
As you enter metadata in the Info inspector’s fields, Aperture checks for previous entries, and if it locates a match, it completes the entry for you. For example, if you used the keyword Landscape previously, and you type the first few letters of Landscape again, Aperture automatically enters Landscape in the field. You can set up and change the list of metadata that Aperture automatically enters using the AutoFill Editor. You can enter up to 20 entries for a field type. If you’ve made a spelling mistake when typing an entry, you can also use the AutoFill Editor to correct the mistake so that Aperture suggests the correct spelling.
