Operating screen objects with function keys

You may also operate screen objects with buttons, e.g. the alarm view, trend view, recipe view or status force using function keys. The condition is here, that the programmer has linked the corresponding system functions to the function keys.

In WinCC flexible, these functions are organized in the "Keyboard actions for screen objects" group.
