I'm pulling in external data that updates often....

I want to be able to launch this file via command line code: "C:\Program
Files\My Directory\MyFileName.exe"
With a switch added: /switch (always the same)
Then a number value added, but that number value is found in a column and
changes from row to row.

So the final command I'm trying to run would be: "C:\Program Files\My
Directory\MyFileName.exe" /switch ####

What I'd LIKE is to assign this command to some key combination such that it
grabs the value for the #### based on the row that currently has focus.
As an alternative, this could be a button or link that resides in each row,
where the value of #### is referenced from a cell in that row, and then that
button or link fills down as the data is updated.

I feel like this would be too hard at all... but I'm also seeing that I have
no clue. Hoping someone can point me in the right direction.

Thank for any direction!
