In the Keyword Tags palette of the
Task pane, click the New button and choose
either New Category or New Sub-Category.
Do one of the following:
To create a new category, type its name
in the Category Name box. Click Choose Color and specify the color
you want to appear on the keyword tags in that category. Then click
to select an icon from the Category Icon list.
To create a new subcategory, type its name in the
Sub-Category Name box. Then use the Parent Category Or Sub-Category
menu to choose a category in which to place the subcategory.
Click OK.
The new category or subcategory appears in the Keyword
Tags palette.
Note: You can edit or delete a subcategory. However,
its icon always appears as a plain tag; you cannot add a photo to
it.
