"EvaluatorInterrupt"

"EvaluatorInterrupt" is a front end token that interrupts the current kernel operation in the specified kernel and opens the Kernel Interrupt dialog box

This token is equivalent to the menu command Kernel Interrupt Evaluation.

This token requires a parameter, which can be the name of the kernel (evaluator) or Automatic if you want the default kernel. See Interrupt Evaluation... for more information.

To execute a front end token, you typically evaluate a command of the form FrontEndExecute[FrontEndToken[token]].
