The Replacement Variable Manager lists all of your styles, together with any replacement variables defined within them. This allows you to see at a glance the way in which any replacement variables you have defined are being inherited by child styles.

Refer to the Color Key at the top of the Replacement Variable Manager page to see how colors are used to indicate whether a replacement variable is customized in a particular style, or inherited from a parent style.
