There are two ways to remove keywords, depending on what you want to do.
Remove a keyword from the index: If you want to remove a keyword from your project so it is no longer part of the index, remove it from the Index Designer. All topics that were linked to the keyword will no longer reference it.
Remove a keyword linked to a specific topic: If you want to remove a keyword from a topic, change the topic properties. If other topics reference the keyword, they are still linked to it. Only the topic you change is updated so it does not use the keyword.
Click the Index tab.
From the keyword list, select the one to remove.
Click Delete
.
From the Topic List or Project Manager, select the topic.
Click Properties
.
Click the Index tab.
From the list of keywords, select the one to remove.
Click Delete.
Tip: When you remove a topic from the project, its keywords remain in the index regardless of whether other topics are linked to them. Unused keywords are keywords in the index that are not referenced by other topics. They are displayed in bold text in the Index Designer and you can automatically remove them. For details, see Removing unused keywords.
