-// There are five classes of accelerators in Ash:
-//
-// Ash (OS) reserved:
-// * Neither packaged apps nor web pages can cancel.
-// * For example, power button.
-// * See kReservedActions below.
-//
-// Ash (OS) preferred:
-// * Fullscreen window can consume, but normal window can't.
-// * For example, Alt-Tab window cycling.
-// * See kPreferredActions below.
-//
-// Chrome OS system keys:
-// * For legacy reasons, v1 apps can process and cancel. Otherwise handled
-//   directly by Ash.
-// * Brightness, volume control, etc.
-// * See IsSystemKey() in ash/accelerators/accelerator_filter.cc.
-//
-// Browser reserved:
-// * Packaged apps can cancel but web pages cannot.
-// * For example, browser back and forward from first-row function keys.
-// * See IsReservedCommandOrKey() in
-//   chrome/browser/ui/browser_command_controller.cc.
-//
-// Browser non-reserved:
-// * Both packaged apps and web pages can cancel.
-// * For example, selecting tabs by number with Ctrl-1 to Ctrl-9.
-// * See kAcceleratorMap in chrome/browser/ui/views/accelerator_table.cc.
-//
-// In particular, there is not an accelerator processing pass for Ash after
-// the browser gets the accelerator.  See crbug.com/285308 for details.
-//
-// There are also various restrictions on accelerators allowed at the login
-// screen, when running in "forced app mode" (like a kiosk), etc. See the
-// various kActionsAllowed* below.
-//
-// Please put if/def sections at the end of the bare section and keep the list
-// within each section in alphabetical order.
