Your first and second posts were 5 months ago. To say:
is quite untrue. Look at what you posted:
This has nothing to do with any notion of 'fit to screen'.

Sure you mentioned '"Fit Visible" (Ctrl+3) in adobe reader' in your second post, but that contradicts your first post. Furthermore, yesterday, you asked:
That is what I responded to, not some self-contradictory postings from 5 months ago. You have now specified your requirements in three mutually-exclusive ways. If you cannot specify clearly and consistently what you want, don't expect any answers offered to match those requirements.
I have already told you what the nearest equivalents are that Word offers - 'wdPageFitBestFit' or 'wdPageFitTextFit'. Choose for yourself whichever best meets your needs.

Do remember that this forum is run entirely by volunteers, none of whom can be expected to invest a huge amount of effort into writing a macro that emulates Acrobat's "Fit Visible" function on a wide range of hardware. For starters, that presupposes the person doing the coding knows the intricacies of how Acrobat treats different kinds of content. And, even if one did, the different algorithms used by Word and Adobe can even lead to the same zoom factors giving magnifications, depending on the hardware used (see, for example, https://www.msofficeforums.com/word/...ord-100-a.html).
