I have the following h:selectOneRadio:

<h:selectOneRadio style="text-align:left" layout="pageDirection" id="#{prefix}_rating" value="#{examinationPanel.tempResult}" >
<f:selectItems value="#{examinationPanel.options}"></f:selectItems>
</h:selectOneRadio>

And then the backing bean is loading the options based on some userpreferences:

public List<SelectItem> loadOptions (Set<ResultEnum> possibleResults){
    messages =ResourceBundle.getBundle("com.eyeprevent.resources.Messages",FacesContext.getCurrentInstance().getViewRoot().getLocale());
    List<SelectItem> options = new ArrayList<SelectItem>();
    for(ResultEnum result:possibleResults){
        SelectItem option = new SelectItem(result,messages.getString(result.name()));
        options.add(option);
    }
    return options;
}

How can I define shortcuts for the options in the radio group? por example typing "1" selects the first option, typing "2" the second, etc...

Thanks in advance! ps. I'm using Jsf 1.2, Richfaces, Primefaces and Facelets.
