Is there a quick way to delete all triggers within a layer?

Hi All

I wondered if there was a quick way to delete all triggers from a layer. I have copied items from one layer to another (approx 100) and they have 2-3 triggers each that I need to remove. 

Is there a quick way to select them all and remove them as at the moment I am clicking through them one at a time which is a bit time consuming.

Thanks
