 Borland released a spreadsheet product, Quattro Pro, that had a compatibility mode in which its menu imitated that of Lotus 1-2-3, a competing product.None of the source code or machine code that generated the menus was copied, but the names of the commands and the organization of those commands into a hierarchy were virtually identical.Quattro Pro also contained a feature called "Key Reader", which allowed it to execute Lotus 1-2-3 keyboard macros.
