   5 // The accelerator priority functions are intended to distinguish between
   6 // accelerators that should preserve the built-in Chrome keybinding semantics
   7 // (normal) and accelerators that should always override web page key handling
   8 // (high). High priority is used for all accelerators assigned to extensions,
   9 // except for the Ctrl+D bookmarking shortcut which is assigned normal priority
  10 // when bound by an extension that requests the privilege to override the
  11 // bookmark UI. This is currently the only case where we allow an extension to
  12 // replace a built-in Chrome accelerator, and it should have the same behavior
  13 // as the built-in accelerator.
