Add a button to a node that triggers an action?

I am trying to find a module or some simple PHP that I can use so that each node (CCK) that I view will have a button I can use to trigger an Action. I have installed Token so that I can configure Send Tokenised email action, but now I need some simple way of triggering that action in the context of a specific node. I know this can be done through VBO, but that is more for bulk sending... I need something that once a user browses into a particular node, they can immediately trigger the Action from that node, rather than having to go off to a View, find the same node, tick it and then trigger the action.

Any suggestions?
