windows - How do I get the list of defined shortcut keys in the Start menu?

How can I find out which keyboard shortcuts are defined inside the Start menu? And what shortcuts they are assigned to?

Platform: Windows XP SP2 64 bit.

Example:

I open my main Visual Studio solution with a shortcut key,
Ctrl+Alt+M. This is set up
by having a shortcut inside the Start menu with:

Target: "D:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE\devenv.exe" D:\dproj\MSQall\MSQuant\MSQuant.sln
Shortcut key: Ctrl+ALT+M

If a new shortcut is added and its shortcut key is also set
to Ctrl+Alt+M then there
are now two shortcuts with the same shortcut key (conflict).
To prevent this it would be nice to know which shortcut keys
are already assigned and to which shortcuts.
