Could you tell me where can I find the top horizontal menu (as on the screenshot)?
As I understand, this is a Menu. And I should look for him in the list of Menus.
But I have no idea how his the name and I think I'm wrong.
From what action did you take the screenshot? I guess your screenshot was taken when your trying to open a new SD ticket? If yes, Kindy try checking in displayoption and search for...
Sample: If your looking for that 2nd icon - Save & Exit:
Screen ID: sd.new
Default Label: Save & Exit
Note: Make sure to try first on your TEST environment.
