[Oberon] Help in using an Oberon systems.

This mail-list is for ETHO-system3,
 which has several branches: DosBased, ?Win? LinuxNativeOberon, LEO, N-O
 which all have the same UI.
The documentation comes with the software; at least for the 'base system':
 NativeOberon.  Since I learned the UI, under N-O, I don't [want to] know
 if LEO [my prefered version] has Tutorials..
OK, this is how I'll check:-----
 System.Directory  *.Text == there are ca. 20 files, 4 of which are:
/mnt/hdc6/home/oberon/docu/Mouse.Text
/mnt/hdc6/home/oberon/docu/Chapter3.Text
/mnt/hdc6/home/oberon/system/System.Text
/mnt/hdc6/home/oberon/docu/IntroToGadgets.Text

Edit.Open /mnt/hdc6/home/oberon/docu/Mouse.Text ==
The Oberon TUI and GUI can be controlled at best with a 3-button mouse
as originally
 designed. However, many potential Oberon users have systems fitted
with 2-button
 mice and are not ready to acquire another mouse in spite of the low cost..
Therefore, starting from Dec. 8, 2000, Oberon offers the possibility
to operate it
 with a 2-button mouse.

                           bute of gadget. Also manipulate gadget.
 MM + MR   Open (2)        Open a document  .......

===========================
That's a quick extract out of the documentation.
IMO do NOT use ETHO without a 3 button mouse, since the MASSIVE power of the
UI comes mostly from the mouse chording.

In general Oberon is a language and NOT an OS.
So how would we know which of several 'systems' you are using ?!!!
