Something I've never figured out--and seems true of LO/OO as well as M$ Word: When reading

reading and one may only have gotten a half page of new reading for the effort.
Maybe I'm spoiled by e-readers. But maybe, even after all these years, I haven't figured out 
how to do this correctly in a word processor.
I think you are missing the different functions of the two sorts of software.  E-readers are 
what they say they are: readers.  In other words, their users are using them to read documents.  
More than that, in general they will be reading the documents sequentially: when they get to the 
end of one page, they will next want to see the next page.  And the only sense of "page" is as 
much as fills the screen of the display device.
Word processors are quite different.  In general, they are still fixated on printing the final 
document: the page size is the format of the eventual supposed printed version, not necessarily 
(and not usually) the size and format of the screen used for display.  People usually choose 
settings that display less than a printed page of a document; if you were looking at such a 
screenful and then moved down a full page, you would unhelpfully have missed part of the text.
But the bigger point is that a word processor is designed for editing, not reading.  If you are 
editing at one point in a document and you now need to move down to a point currently off your 
screen image, it is not at all obvious - quite unlikely, in fact - that you would want to move 
to a following page.  It is much more likely that you would want to be able to see some part of 
the document further down but whilst also still seeing the part on which you had just been 
working.
The original model, then, is that no-one would read documents on screen but only from hard copy. 
It is interesting that software has been moving towards servicing screen reading, albeit rather 
slowly.  Microsoft Powerpoint allows you to save a presentation as a "slide show", in which case 
it opens for any recipient as for display, not for further editing.  Microsoft Word has a 
reading mode, which displays screenfuls - not necessarily in the original layout - and in which 
your page down function works as you want.  There is also a freeware Word Viewer available from 
Microsoft, intended for users without Microsoft Word installed.  Again, since this is a reader 
and not an editor, it responds to page down requests by moving down a screenful.  Oh, and try 
opening a read-only file with LibreOffice Writer: I think you'll find that it will now treat 
"page down" differently and move down (almost) a screenful.
Should word processing and similar software provide an explicit reading mode for use in reading, 
not editing, documents?  Possibly.  Meanwhile, if you want something close to this behaviour in 
Writer, here's your workaround: just click the Edit File button in the Standard toolbar to 
toggle on this behaviour.
I trust this helps.
