I haven't.

I think we never enabled it because we could not use good key combinations��� the idea
was to use ctrl-arrow keys for it���

I still think that AST based navigation is a very good idea, removing it now without having
ever used it for real is not good.

Marcus, would that make sense to:

* extract the core of the AST navigation as an API onto the RB AST (the ability to go up, down, left and right in a RB AST, basically), i.e. trying to preserve that way a bit some of the patterns solved by the AST navigation...

* and reduce whatever is linked with the GUI / text morph components ?


Yes, sounds good...

Oh, looking at the code, the two aspects are implemented together, so it will be painfull to refactor. Looking a bit more at the code... I'm interested by the rationale for askForNodeSelectionFrom:
