ShortcutCut keys does not support CTRL key, only ALT. This comes from the platform and as far as I know cannot be changed. Also RadMenuItem that is not visible cannot raise a command.
I have attached sample project demonstrating how you can bind RadMenuItem to commands that come from database (although I'm not sure how can this commands be serialized into database).
In order to support you scenario with CTRL key I have added two KeyBindings at Window level. This way you could trigger SaveCommand using CTRL+S, or ALT+F (to open File menuitem) and then ALT+S to trigger save command on RadMenuItem.
I hope that this will help you.
