Hotkey Help - Shortcut Sorrows!

I use a pro-level digital audio workstation (DAW) environment called "Cubase" by Steinberg. This has multiple shortcut keys pre-defined as well as the ability to create User-Defined shortcuts. One of these command shortcuts 'overlaps' with an nVidia display driver utility called "nView desktop manager debug".

Unfortunately, there appears no way to amend the `Shift``Ctrl``Alt``N` shortcut assigned to this utility. I need to identify where this shortcut resides in the registry - either by finding the actual Explorer Shortcut (and manually removing its shortcut keys under the shortcut's Properties window) or by navigating to the correct value in the registry and removing the global shortcut key assigned there - in order that my music production environment functions as required.

[Yup! First-world problems, eh!?]

Ergo, three questions:

1. Where are such global keyboard shortcut key combinations stored in the registry?
2. Is there a way to display all of a system's currently employed keyboard shortcut keys (including all the pre-defined Windows ones, if necessary!)?
3. Is there a way to list all Explorer Shortcuts which actually have had keyboard shortcut keys allocated to them (whether by an individual user or by the app which installed them)?

I've spent weeks on this issue, including installing HotKeyCommander and multiple other utilities (which either did not provide the requisite information, did not run successfully on a 64-bit system, or did not provide sufficient information for me to locate and modify/delete the offending registry entries).

Thanks in advance,

Steve.
