[4.2] - Cancelling a trigger

Hello,

I have a trigger that I am manually starting by using the "Run Triggers" option from the trigger menu. However, sometimes you might want to cancel those if the trigger doesn't behave as you are expecting it to behave. Whats the best way we can cancel this trigger that has been running through thousands of records?

PS: This is not a timed trigger.

Cheers.
