This likely should be an icecore: component.

Introduced new DefaultAction component. Modified FormSubmit system event listener to provide a key code – element id mapping when enhancing the form for capturing key presses. Modified bridge to read the mapping in ice.captureEnterKey and submit form when key code matches one of the mappings.

Renamed ice.captureEnterKey to ice.captureKeypress.

Added the following key mappings: "Enter", "Esc", "Space", "Page Up", "Page Down", "Page Up", "Left arrow", "Up arrow", "Right arrow", "Down arrow", "F1", "F2", "F3", "F4", "F5", "F6", "F7", "F8", "F9", "F10", "F11", "F12".

The component can be used in within a form to capture a certain key press. Multiple icecore:defaultAction instances can be used to capture different keypresses.

Usage:

<h:form id="form"> 
... 
    <icecore:defaultAction actionListener="#{sampleBean.update}" key="Enter"/> 
    <icecore:defaultAction action="#{sampleBean.cancel}" key="Esc"/> 
    <icecore:defaultAction action="#{helpBean.help}" key="F1"/> 
... 
</h:form>

It would be good if the individual key names did not have spaces, so that the key property could take a space delimited list of keys that would trigger the action/actionListener. This way apps can choose between using different defaultAction components with different actionListener(s) versus one defaultAction with one actionListener that itself looks in the request parameter map to determine which key was pressed and act accordingly.

Modified key names made of two words to not have spaces and always use camel case. So now the keys names look like this: PageUp, PageDown, ....., LeftArrow.

As far as multiple key mappings wired to the same action/actionListener, this already can be done:

<h:form id="form"> 
... 
    <icecore:defaultAction actionListener="#{sampleBean.update}" key="Enter"/> 
    <icecore:defaultAction actionListener="#{sampleBean.update}" key="Esc"/> 
    <icecore:defaultAction actionListener="#{sampleBean.update}" key="LeftArrow"/> 
...
</h:form>

It might not be as terse as the suggested approach but acceptable in those rare cases where needed.
