On Windows 10 operating systems the context-sensitive help, for example used when clicking on help links in dialogs or in the Silk Performer user interface, does not work. This is also true for BDL functions searches: Marking a BDL function in a script and pressing F1 on your keyboard does not work on Windows 10 and Windows Server 2016.
Open the Help and search for the desired information manually by using the search or index fields.
