Allow me to rephrase:

Since your application would know where both subfiles are at all times, it
would be able to return to the "current position" without having to
remember anything else, and it would be able to go back to any previous
position that it found "noteworthy" in some way, simply by defining the
conditions by which that position is considered "noteworthy," and saving
whatever variables define that position.

Assume, for argument's sake, that we define F1=bookmark, F2=return to
bookmark, and F5=refresh screen without moving
Pseudocode:

If (AIDkey = <PgUp> or <PgDown>) then
    If (CsrRow > DividingLine) then
        roll lower subfile in desired direction
    else roll upper subfile in desired direction
    endif
    redraw both subfiles
endif

If (AIDkey = <F1>) then
    if (csrrow > dividing line) then
        remember position of lower subfile
    else remember position of upper subfile
    endif
    redraw both subfiles
endif

If (AIDkey = <F2>) then
    if (csrrow > dividing line) then
        return to remembered position of lower subfile
    else return to remembered position of upper subfile
    endif
    redraw both subfiles
endif

If (AIDkey = <F5>) then
    redraw both subfiles
endif
