deleting bluetooth devices

[macmesser]

I want to delete my bluetooth devices and add again but can't delete selected devices in prefs. How do I do this? I'm adding BT dongle.

You've moused over the device in the bluetooth System Prefs list, and clicked the little x in a circle that appears?

Thanks for reply. Finally, when I at last noticed them.
