1)In the User Defined Variables pod, select Default Variable Set.
2)Right-click a user-defined variable, and select Delete.
3)Select one of the following options:
Delete Variable And Its References
Delete the variable and its references across the topics, TOC, index, SSL, and templates. No warning is shown before the deletion.
note: Use the Variables report to locate the variables you want to remove.
Delete Only The Variable
Delete the value of a variable locally. Deleting a user-defined variable in the TOC does not remove it from the index.
note: If the variable value is overridden in the Single Source layouts file, it is removed from the variable list in the Single Source layouts dialog box.
Delete Variable And Replace With Actual Content
Delete the variable across the topics, TOC, index, SSL, and templates. The formatting rules for the variable remain the same.
