//
// 1- Replace the old deprecated accelerator from the above list with the new

// 2- Add an entry for it in the following |kDeprecatedAccelerators| list.
// 3- Add another entry in the |kDeprecatedAcceleratorsData|.
// 4- That entry should contain the following:
//    - The action that the deprecated accelerator maps to.
//    - Define a histogram for this action in |histograms.xml| in the form
//      "Ash.Accelerators.Deprecated.{ActionName}" and include the name of this
//      histogram in this entry. This name will be used as the ID of the
//      notification to be shown to the user. This is to prevent duplication of
//      same notification.
//    - The ID of the localized notification message to give the users telling
//      them about the deprecation (Add one in |ash_chromeos_strings.grdp|.
//      Search for the comment <!-- Deprecated Accelerators Messages -->).
//    - The IDs of the localized old and new shortcut text to be used to fill
//      the notification text. Also found in |ash_chromeos_strings.grdp|.
//    - {true or false} whether the deprecated accelerator is still enabled (we
//      don't disable a deprecated accelerator abruptly).
// 5- Don't forget to update the keyboard overlay. Find 'shortcut' in the file
//    keyboard_overlay_data.js.
