In the property menu, the current action or the property can be selected, for which the formula is displayed.
The "="
The "=" between the property menu and the formula editor is displayed for properties. This emphasizes that the result of the formula is assigned to the currently selected property. For actions, there is no result returned, so the "=" is not displayed.
