In the french version, the translation is "cover format". This fonction is linked to the parent object, and if this parent object is generaly the screen, this is not always the case, and it is very important to understand that many values in different controls refer to the parent object, and not to the screen. Even size and zoom, are expressed according to the size of the parent object, wich is not always the screen. As shown in the attached image, it will be non-sense to write "cover screen" when what we get is "cover parent object". This is why "cover format" is certainly the most convenient label, and it is very important to understand the parent-child structure of PTE, and to keep in mind that different values attached to any object are always expressed according to its parent, which is not always the screen. I attach a second image (infortunely in french) to show the structure of PTE objects.
