How many data structures you have? Each data structure
can be object.

I don;t really know if that would be useful.

Yes, but again with OOP you have to simplify , not
complicate.
Again you can recognize in your program what objects
would be.

Yes.
it would be line.Move(fromplace,toplace),
but than again you could have text object,
which is collection of lines,
and then text.Move(line,fromplace,toplace)
You may recognize in your program what are
objects (I guess you have data structures already).
