Label Manager
Magic Labels includes a label management feature on a per-space basis, Label Manager. It gives you an overview of all the labels in your space and on how many pages and blog posts these labels are being used.
List all Labels in a Confluence Space
Open the Label Manager by clicking on "Label Manager" on the left-hand navigation sidebar.
Rename a label in Confluence
To rename a label, click on the label name, enter the new name and click the small check mark. Your label will be automatically updated in the background.
Remove a label from all pages
To remove a label from your space, click the trashcan icon on the right side. Because this action cannot be undone, there is a confirmation screen before your label actually gets deleted.
