Actually, geomview does not get any keyboard events until it is the  
active app. Since you were starting up geomview from a shell window,  
the terminal application was the active app and remains the active  
app until another is activated. There are a number of ways to  
activate an app: click on one of the apps windows, double click on  
the apps Icon, hiding or quitting other apps, etc. So, I believe that  
this is why the "<" was showing up in your terminal window and not  
activating the open panel.

This behavior is no different than geomview on the sgi. Comparing  
behaviors; I have found to be a good test to see if: a bug is a NeXT  
geomview bug, a geomview bug, or just a misunderstood geomview  
behavior. In this case I think that it is just a misunderstood  
geomview behavior, which is, when typing "g1" only the target of on  
action is being specified and it is only when an action gets  
specified that g1 will (possible) get selected... A few such actions  
are "p" for pick, or "t" for translate, or even "d" for delete.
