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