Question

Given a WPF Button with a Command, how can I get the assigned shortcut (ex Copy -> Ctrl + C)

Answer 1

Here you can replace ApplicationCommands.Copy with the command you are looking for.

foreach (KeyBinding binding in InputBindings)
{
    if (binding.Command == ApplicationCommands.Copy)
    {
        MessageBox.Show(binding.Modifiers.ToString() + " + " + binding.Key.ToString());
    }
}
