I have a text element with two paragraphs and have assigned a style to each paragraph. One paragraph style is a different color, for emphasis.

When I go to Swatches (palette) > Add Used Colors, all of the text turns white (invisible against a white artboard) and a swatch named "K=0" is added to the swatches palette. This can be avoided by setting all Paragraph Styles to black or no color and using Character Styles to apply color, but that's not really how the styles are supposed to work.

If the paragraph and character styles ever are fully functional in Illustrator, it would also be lovely to be able to assign shortcuts to styles, like in InDesign.
