Edited original image to include second layout example, the one that I'm actually using myself.
Thought I'd include it here for anyone who wanted a layout that fits better with other toolbar buttons (change x and y co-ordinates in first line to reposition within toolbar).
May need to refresh page to get edited image if you've recently viewed the original image.
Code:
<Element ID="Toolbar_Quickslot_Page" X="1340" Y="155" Width="25" Height="64">
<Element ID="Toolbar_Quickslot_Page" X="-5" Y="0" Width="31" Height="64">
<Element ID="Quickslot_Page_Up" X="8" Y="12" Width="20" Height="17"> </Element>
<Element ID="Quickslot_Page_Down" X="8" Y="23" Width="20" Height="16"> </Element>
<Element ID="Quickslot_Page_Indicator" X="2507" Y="16" Width="10" Height="25"> </Element>
<Element ID="Quickslot_Page_Icon" X="2503" Y="16" Width="26" Height="26"> </Element>
</Element>
</Element>
