Solution
To remove a control from the tabbing order, right click the control>>Advanced>>Key Navigation. This will then bring up the properties menu below:
![](/servlet/rtaImage?eid=ka00Z000000kFkf&feoid=00N0Z00000HEWRt&refid=0EM0Z000000py1x)
From here you can change the tab behavior to be "Skip this control when tabbing" to remove it from the tabbing order.
