To toggle between Interactive and Silent script playback mode, simply click the
Interactive Script Playback Toggle button

on the Script toolbar. When the button has a border around it

, it is in Interactive mode.
Note that if part or all of a script has been set to run in either Silent or Interactive mode, this button’s state will not override that setting. If all or part of a script is set to Default mode, however, the state of this button will override the Default setting.
