orion configuration

Hi all,

I am a little confused with the config file for orion.  i think it has 
to do with all the implicit backquoting that is going on.

Here is the part of the code that is giving me problems.

    (define (get-term)
      (let ((term (aterm -tr -trsb -sh 50 -fg yellow -bg black)))
        (& ,term)))



     (define root-options
       `((quit . "F12")
         (save-layout . "F11")
         (nth-workspace . ("M-1" "M-2" "M-3" "M-4" "M-5" "M-6" "M-7" 
"M-8" "M-9"))
         (create-workspace . "F10")
         (kill-client . "M-Escape")
         (attach . "F9")
         (user-bindings . (("F2" apply ,get-term)
;                          ("F4" apply ,xsel->opera-remote)
...
                           ("F8" exec "emacs")))))




I tested the above in scsh, and it worked, but does not work in orion, 
but I think there is yet more backquoting going on, which has me 
confused.  Doing ("F2" exec "aterm -tr -trsb -sh 60 fg yellow -bg 
black"), gives an error about not finding an application of that name, 
and if I then do ("F2" exec "aterm" " -tr -trsb -sh 60 fg yellow -bg 
black"), on a whim it gets also gives an error.
I have tried passing strings, and other contortions, but so far to no 
avail.  I a reading the scsh manual to see if I can figure out what is 
going on, but in the meantime if anyone can tell me what I am doing wrong...

This brings up more questions that I am hoping to get sorted out 
eventually, but if anyone has a quick answer.  The orion-client project 
is becoming more and more necessary so I can test while running the wm.

Is there anyone who has  set up a menu in orion, so you middle click on 
a window and it gives you a menu to choose from, and failing that is 
there a way to bind control-meta-<somekey>, as my attempts have failed 
so far.  I am interested as I do not want to clobber my emacs bindings 
when I want to perform different commands.

Thanks,

Rohan
