When I reload a PDF document (notably when writing one) the viewer
forgets the zoomed size and the position on the page, and falls back
to the full-page view.  This is not at all pleasant when working on
details such as the display of formulae in LaTeX.

When pressing CTRL-+ (or CTRL-SHIFT-=, unfortunately CTRL-= is not
supported as an alias) the old zoom factor is suddenly recalled and
increased.

So, after a reload, all of CTRL-+ CTRL-- and repositioning with the
arrows are needed to lookup the details that you are working on.

Thanks for all that does work though!
