// Add ability to copy the current URL using vim like shortcuts
// There already exists navigation related shortcuts like
// F/S -- For Searching
// P/N -- For navigating to previous/next pages
// This patch just extends those features

// Expose the internal notification API of mkdocs
// This API isn't exposed publically, IDK why
// They use it internally to show notifications when user copies a code block
// I reverse engineered it for ease of use, takes a string arg `msg`

  // Disallowing that would be hilarious
