Horst demonstrates that the OpenOffice suite is easy to learn. You can quickly get started on any of its applications with minimal reading of a manual or text, like this one. The authors of OpenOffice spent considerable effort ensuring that a new user could rapidly do useful work.Of the applications, possibly the most heavily used is Writer. It does not have all the features of its Microsoft analog. But the basic operations of changing fonts, colours, etc, are present. If you have any previous experience with the Microsoft application, then Writer's abilities will be very familiar.Likewise for the other OpenOffice applications. None of these can match Microsoft's offerings for sheer quantity of features. But perhaps Horst shows that you can get enough for your needs.
