[Google-Desktop-Developer] Google Desktop keyboard shortcut to system tray search field

Google Deskbar has 2 keyboard shortcuts to access the search field in
the system tray: windows+g or ctrl+alt+g

Why isn't there a keyboard shortcut for Google Desktop when it is in
the system tray? I suggest:
ctrl+alt+d

I can't find sign anywhere to other people discussing this or
requesting this. I am actually really shocked!
