I probably should consider this, but users don't tend to like all kinds
of startup messages (I usually don't pay attention to them unless
they are very short and just tell me where to get some information).
Anyway, M$ has no patents on keybindings and all major Linux applications
except Vi and Emacs tend to adopt the M$ way of life. Not being compatible
will rather harm than help the expansion of TeXmacs, I fear...

Well, there are modifyable states, like in scheme, with set!.
Hence, it is not like Haskell, if that is what you want.
In fact it really has the same spirit as Scheme.

Take a look at the file TeXmacs/kernel/gui/gui-test.scm
in the latest CVS version (as advertised in a recent post on texmacs-dev).
In a Scheme session, you may try

        (use-modules (kernel gui gui-test.scm))
        (widget-popup "Copy" '(widget-5))
        (widget-popup "Counter" '(widget-6))
        (interactive-popup replace-start-forward)

Of course, any help would be appreciated.

Best wishes, Joris
