Personally, since I rarely (if ever) have more than four sub-windows,
with one vertical and one horizontal split, either in Vim or in
GNU/screen, I always (and only) use <C-A> ¹ + <h,j,k,l>  to move quickly
between regions.

Maybe this does not sound quite as effective (at least in theory, see
note below) as jumping directly to a given sub-window, but I find that
since the keyboard actions are almost identical in both Vim and screen,
I am able to navigate between sub-windows with no overhead.

Here's what I added to my .screenrc:

 bind j focus down
 bind k focus up
 bind h focus top
 bind l focus bottom
 bind o only

Not exactly what you were asking, but this "solution" meets my
requirements of having (somewhat) consistent keyboard actions across the
environments that I use on a regular basis.

That's just fine. I can use your bindings for now. Thanks.


¹ white lie: I really use <CTRL + spacebar> as my command key combo,
 actioning CapsLk (remapped to Control) with my left pinkie and the
 spacebar with my right thumb, so that I don't even have to move my
 fingers off the home row. Even when I have to to a "<C-SB> + J"
 followed by a "<C-SB> + L" to move diagonally, I still find it less of
 a hassle than having to *think* of the correct digit/number *and*
 reach for the corresponding key in the top row of the keyboard.
