As of ICEfaces 4.0, the ACE components have very limited support for the XHTML "accesskey" attribute.

In a web browser, accesskey allows a user to immediately jump (set focus) to a specific element on a web page via a keyboard-shortcut.

As of ICEfaces 4.0, the following ACE components support accesskey:
- autoCompleteEntry
- comboBox
- maskedEntry
- simpleSelectOneMenu
- textEntry
- themeSelect

In ICEfaces 3 ace:checkboxButton, ace:pushButton, ace:radioButton, and ace:linkButton also supported accesskey, however, their support was lost when certain "unsupported" HTML passthrough attributes were removed from their TLDs in 4.0.
