I am writing code and I realize that I forgot the name of the variable
that I defined 30 lines ago, I use the mouse to do a quick scroll up,
read the name, and scroll back down where I came from.  The problem is
that now the cursor location has changed, and I have to spend time
trying to figure out which line I was typing on and moving my cursor
back to that position.  It would be nice if I could have the cursor
stay where I left it for the brief period that I peek elsewhere in the
buffer.

I was looking for a hook, and did not see a relevant one. I was not
aware that window-scroll-functions existed, but it looks like it could
be a viable solution.  Thank you.
