Help with Rule

How can I kick off a "Stop Actions: Rule I want"

It is now called "Cancel Rule Timers" and is found under "Set Private Boolean/Run, Cancel, Pause Rules"

So this is the same thing then?

The same way you would trigger any other rule...through defining the trigger events and any conditions you want to check. it is the same as any other action.
