Position screen at end of macro

So far, at the end of a macro I've been sending the cursor across to various
columns and back to position the screen. Itys a bit clumsy, and of course
when you work between different sized computer monitors it doesn't work the
same.

Is there a quick way to position a partcular cell at top left of screen -
and perhaps on a separate occasion a particular cell at bottom right?

Thanks.
