In Lexicon Edit, the The dictionary preview pane is at the top, above the individual fields. Sometimes it can be difficult to know which field stores a specific part of the entry. In this case, you can use the Jump to field option.
In the Navigation Pane, click Lexicon, and then click Lexicon Edit.
In the Entries column, click the desired entry.
In the dictionary preview pane, right-click the part of the entry that you want to edit, and then Jump to field.
The focus, or "insertion point" of your cursor moves to the field that stores that part of the entry.
