I fully support this request.
here is a work around:
use a title cell at the beginning of your document then when you need to
run all the code above your cell, insert another title cell below.
you can now select easily all the cells you want to run.  you can then
remove the cell below.

Subject: [mg13646] [mg13610] New Notebook Select or Evaluation Command?


I like to suggest a new front end or notebook editing command which
would say in essence: 

   "Select All Cells from this Cell up to the Top of the Notebook"
   
whenever it was activated by some suitable keyboard shortcut.

The usefulness of this command would arise when one was developing a
notebook and editing or modifying cells in the middle of the notebooks.

In common I suspect with many others, I often build a lengthy notebook,
then realize there are multiple changes in notation and formulas and in
the way I want to approach the problem.  

As I work down through the notebook, modifying individual cells, I often
want to reevaluate the notebook from the top down to the point where
I'm currently working.

The easy way to do this is "ctr-A, Enter" -- except that this evaluates
everything and so overshoots the current working point, and if I've
modified things usually leads to a lot of errors beyond the current
working point.   

(And in my experience, "Abort Evaluation" is not a reliable command in
Mathematica 3.0).

Scrolling up and selecting all cells from the current point to the top
of the notebook requires multiple mouse actions and some delicate
mousing, especially on laptops with trackballs or trackpads.

I suppose an alternative approach, at least on a Mac, would be to have a
"Jump to First Cell" keyboard command, with the capability that
"Shift-Jump to First Cell" would select all cells up to the first cell.
