Where are user keyboard shortcuts stored

[nbrcrunch]

I tried searching this website for "shortcuts file" or "shortcuts storage" and found nothing.

When writing VBA, I would like to specify a shortcut. I've noticed on recorded macros the line that Excel puts in that is just a comment line acknowledging the shortcut exists. But where is this stored? Or at least, how do I create one myself without having to use the Macro menu option?

To complete headtoadie's thought (which is partially correct)

In Thisworkbook:

Sub Workbook_Open()

Application.OnKey "^h", "hello" 'sets ctrl+h to run hello()

End sub

(make sure hello() is in a module and not a sheet or Thisworkbook)
That way, once you open your workbook, the shortcut is assigned. The code will work for all of excel as long as you have opened that specific workbook. If you want to run a macro shortcut regardless of which workbook you open, this will not help.
