Hello / Portkey

Dear All,

Just joined and overwhelmed by the range and depth of arguments, but
enjoying it all.

I have a query related to GoF (It's the last one I read and vols 5&6
have been lent to others). I imagine this has been debated at length
but I searched for portkey and couldn't find any reference to it. 

The portkey in GoF that took Harry and Cedric to LV also took Harry
back: how did it work? If young Crouch set it up he surely wouldn't
arrange a return journey; and I thought portkeys were time-specific,
you couldn't just touch one and be off. 

The portkeys at the world cup appear to be time-specific and one-way
use, so how did this one example work as a return and at any time?
