Also, for those who dont want a million buttons you can use this instead:

<script type="text/javascript">
function dropDownDice(obj){
if(obj.value != ''){ 
    var data = obj.value;
    var indx = data.indexOf(';');
    var diceToRoll = data.substr(0,indx);
    var faces = data.substr(indx+1);
    document.getElementById('{$editorid}_textarea').value += '[dice='+diceToRoll+']'+faces+'[/dice]';
}
}
</script>

<td><select onChange="dropDownDice(this);">
<option></option>
<option value="1;6">1d6</option>
<option value="2;6">2d6</option>
<option value="3;6">3d6</option>
<option value="4;6">4d6</option>
<option value="5;6">5d6</option>
<option value="6;6">6d6</option>
</select></td>

Place it where you would place the other ones, just above the:

<if condition="!is_browser('opera')">

Should help with those who dont want to clutter there editor.

NOTE: These do not work if you have WYSIWIG turned on.

To add a new dice just add:

<option value="Number of dice to roll;Number of faces">Descriptor</option>
