[plt-scheme] arglist-on-space?

Is there any way to get "arglist-on-space" behavior in DrScheme or any  
editor working with PLT scheme? What I mean by this is that when you  
type the name of a function and then a space the argument list for the  
function appears in a mini-buffer (or anywhere -- I just want to see  
it). I'd be happy to have this functionality either in an editor (e.g.  
the DrScheme definitions pane) or listener (e.g. the DrScheme  
interactions pane) or both.

I am a DrScheme/PLT newbie, adopting it for a course I'm teaching in  
the fall, but I'm a long-time Common Lisper and this is one of things  
I miss most from my favorite CL environments. Next on my list would be  
a way to get from a function name to the definition of the function  
with a couple of key strokes, rather than searching in files. Both of  
these things require the runtime environment to keep information  
around that maybe PLT isn't keeping around... but I don't know.

Thanks,

   -Lee
