This policy setting lets admins enable extended Microsoft Edge Internet Explorer mode hotkeys, such as "Ctrl+S" to have "Save as" functionality.
If you enable this policy, extended hotkey functionality is enabled in Internet Explorer mode and work the same as Internet Explorer.
If you disable, or don't configure this policy, extended hotkeys will not work in Internet Explorer mode.
