There are two ways to edit the metadata applied to a file.
The SpotMeta hotkey can be changed by choosing "Preferences..." from the SpotMeta application menu.
With either method, a SpotMeta editing window will appear.
To apply your metadata to the file, click on the headings to expand the metadata entry field. To remove a value, click on the - button to the right.
When you have finished, close the window to apply the metadata and make it available in Spotlight.
