Tutorials are small files, each showing a bit of MINOS2. For the common framework, the file minos2/tutorial/tutorial.fs needs to be loaded first; all other tutorials in the command line argument are included from within that file. Scroll wheel or previous/next mouse buttons as well as clicking on the left or right edge of the window allow navigation between the different tutorials loaded.
I.e. to load the buttons tutorial, you start Gforth with
gforth minos2/tutorial/tutorial.fs buttons.fs
