The External targets button in the View tab option makes it easier to find external targets: If this button is activated, the external connection points of functions are marked with an arrow. This makes (e.g.) target tracking for terminals easier. This allows you recognize the page of a terminal diagram where a target is output.

You set the Internal / External property in the Connection point logic dialog, which you call up from the Symbol / function data tab of the property dialog, via [Logic].
