BUG: Character styles not working, plus sign and redefine style greyed out
In Pages, Keynote and Numbers, the character styles functionality seem to be broken.
When I select a character and want to create a new character style from its formatting, the menu doesn't let me. The plus sign is not clickable. This is clearly a bug and should be fixed because it completely annihilates reusability of formatting in Pages, Numbers and Keynote.
In the screenshot below, I select (highlight) a character which is part of a paragraph styled with the style named Body, displayed as Body+ in the paragraph styles.
The changes to its formatting should allow me to save them as a character style, but the plus sign is greyed out. The menu item Redefine style is greyed out as well.
This behaviour started in the last few MacOSX versions.
What can I do to fix it?
