[plt-dev] arrows crossing selection

Very nice tool for checking that a form has no other external dependencies 
than intended.
Two remarks though:

1: Because all references to imported bindings (both variables and syntactic 
forms) have arrows too, there is an abundance of non informative arrows (for 
example to the #lang scheme line) that obscure the arrows I am interested 
in, id est those that point between bindings and references within the 
current module only. Id est, the arrows to require forms can be omitted as 
far as I am concerend.

2: How do I untack?

Thanks
Jos.
