You may highlight a block in the Audience Designer workspace and invoke its removal. This can be done using the button on the block itself, or via the toolbar. You can remove several blocks concurrently by highlighting them and using the toolbar button.
Note that no ‘Are you sure?’ dialog is displayed when you elect to remove one or more blocks.
Following the removal of one or more blocks, an asterisk is appended to the audience’s name displayed within the current tab, indicating that unsaved changes now exist.
