// Shortcuts:
//   d -> delete current page
//   h -> history
//   r -> recent changes
//   e -> edit current page
//   u -> upload file
//   p -> protect current page

// Wikitext editor only:

//
// Notes:
// - D/H/R/E/U/P won't trigger while typing.
// - Ctrl/Cmd+Enter WILL trigger while typing in the wikitext textarea.
