Note:
The default vBulletin style does not use any replacement variables, so the list will appear empty on a fresh vBulletin installation.
As with the StyleVars Editor and CSS Editor, replacement variables customized in the current style will be shown in a different color, along with a Revert checkbox. To delete a customization, click the checkbox and hit the button.
When a replacement variable's value is being inherited from a parent style, another different color will be used, and a hyperlink will be shown.When clicked, this hyperlink will tell you the style from which the value of the replacement variable is being inherited.
