Automatically select a radio button if a checkbox is selected.

I have a form with 2 radio buttons and multiple checkboxes (see example below). The one radio button indicates all and the other radio button indicates the user has chosen specific options (checkboxes) from a list. Can I use javascript to automatically select the 2nd radio button if the users clicks on any of the checkboxes?

<form name=form1>
<input type=radio name=Radio1 value=All>
<input type=radio name=Radio1 value=Specific>
<input type=checkbox name=Checkbox1>
<input type=checkbox name=Checkbox2>
<input type=checkbox name=Checkbox3>
<input type=checkbox name=Checkbox4>
</form>

 <form name=form1>

    <input type=radio name=Radio1 value=All tabindex=1>

    <input type=radio name=Radio1 value=Specific>

    <input type=checkbox name=Checkbox1 onclick='sel2()'>

    <input type=checkbox name=Checkbox2 onclick='sel2()'>

    <input type=checkbox name=Checkbox3 onclick='sel2()'>

    <input type=checkbox name=Checkbox4 onclick='sel2()'>

</form>
 
<script type='text/javascript'>

    function sel2(){document.forms['form1'].elements['Radio1'][1].focus()

}

</script>

this will not always work in ie, as it allows only the first radio input of a group to be focused via js, when nothing else is selected...
