Visual Studio find out what command is assigned to an hotkey

I've installed a Visual Studio plugin that redefines some hotkeys. I need to come back to the standard hotkeys of Visual Studio for some of them. I know that under Tools->Options->Environment->Keyboard I can redefine the hotkeys, and I did it. The problem is that now it seems that my hotkey Ctrl-E, C has two command associated, the plugin one and the standard one. When I press that combination visual studio runs the plugin command and not the standard one.

The problem is that I don't know the plugin-command name so I can't dissociate it unless I go through all the command to see the associated hotkeys. Is there a way to discover commands associated to a specific hotkey?

You can try to assign this shortcut to another command and then you will receive info that this shortuct is already used by [your command]:
