[CHECK: Test Case]
(1) Enable workspaces (System Settings > Appearance > Behavior > Enable Workspaces).
(2) Hold down the Super key until the Shortcuts window appears.
(3) Under Workspaces it should display "Shift + Ctrl + Alt + Arrow Keys" and not "Shift + Ctrl + Alt + Left + Arrow Keys".

---> It was changed to "Shift + Ctrl + Alt + Arrow Keys".
