[mcclim-devel] Customizing interactor panes

I'm writing a GUI for a chemistry program with McCLIM. My problem is that I want the user to be able to type commands into the interactor pane in a special syntax, which I have written a parser for. For example, typing "Krypton" should call the Inspect Element command on the element called "Krypton". Typing "12 g C H4" should display how many moles of methane there are in 12 g. There's more like that, but I have the code to handle it all written---except for the code that hooks it into an interactor pane.

There's a way of getting an interactor pane to differentiate between commands and s-expressions, for use in a listener, so I think that what I want is possible. Can anybody tell me how?
