The UI Debug tag allows you to display helpful information about the JSF component tree and scoped variables in your browser when you test your JSF pages. The hotkey attribute specifies a key combination (CTRL + SHIFT + D is the default value) to display the popup window containing the information. The UI Debug tag can be enabled or disabled by setting the rendered attribute.
Example:
<h:commandButton value="Continue Shopping" action="#{shoppingCartBean.saveCart}">
<ui:debug />
</h:commandButton>
