My application needs go a bit beyond markup higlighting so I am trying to
find out more about more of the Editor control functionality.

My observation of the FEdit example indicates that the editing stack
(multiple views) was implemented by using a vertical split control, a
second editor control and assigning the View property of the second editor
with the first.

In abscence of a VSplit control you can use:

Editor2.View=Editor1

in form_Open().

The two editors can be of different style but the highlighting uses the
highlight mode of the first Editor control.

All you do is set the View property of additional editors to the first and
that effectively links them together.  I just tried this in my own form
and it works (I'm using 1.9.25) exactly as it should.  The VSplit control
is optional but using it allows independant resizing of the views.  I
imagine even three or more editors may be linked the same way.
Furthermore you might even get away with linking across forms if you make
them visible outside the form either by enabling "Form Controls are
Public" for the project or creating them in the forms using something
like:

Public Editor1 AS New Editor   'in Form1
Public Editor2 AS New Editor   'in Form2

and in form_Open() of Form2:

Editor2.View=Form1.Editor1

Yes that is a useful feature.  Again the View property is the key.

It is possible that GambasEditor does not support the View property like
the Editor control does.

You could use a workaround -- two Editors with the highlight mode set to
the constant Highlight.Gambas then have any "slave" editors just patch
into the first using the View property of the slaves.
