 The _ace:pushButton_ component allows submission of a form in it's entirety or also the submission of itself only. This component supports an action attribute as well as an _actionListener_ attribute similar to a _h:commandButton_.

 <!-- can use either class of ice-skin-sam or ice-skin-rime -->
 <h:body class="ice-skin-sam">
  <h:form >
  <h:panelGroup id="push1">
  label="this button submits the entire form"
  actionListener="#{button.actionListenerMethod}" />

 *value* refers to the text written on the button, similar to that of jsf commandButton.
 *label* If no value present, the label will be used for the pushButton. Otherwise if both are used, the label will be used to define the aria-role, described-by.

 *singleSubmit* When singleSubmit attribute is true, the pushbutton only submits an event request via submit call with execute=@this and render=@all, in other words, only the button is submitted with any action/actionListener attributes. If false then full form submit happens where execute being set to @all.
 Default valid is false.

 h3. ARIA and Keyboard Navigation Support
 Pushbutton component supports keyboard short-cuts and ARIA. Aria support can be enabled at page level or at application level. By default ARIA is enabled at application level.
 To enable/disable ARIA at page level, the [<icecore:config>|Core Tags#icecoreconfig] tag can used:
 <icecore:config ariaEnabled="true"/>
 To enable/disable ARIA at application level, the following param can be set in web.xml.
 * space or enter key will fire the button's onclick event
 Aria _role="button"_, aria-describedby and aria-disabled properties supported
 The ARIA implementation is based on the specification at [button aria practices|http://www.w3.org/TR/wai-aria-practices/#button]. Currently only the basic ARIA attributes and single-key keyboard shortcuts have been implemented.
