generating a key-pressed event.

[J Leven]

Hi,
I'd like to automate the gtkEmbed program so that the user does not have to
type in a URL in the urlEntry box.  I'd like to instead read a set of URLs
from file and generate the [ENTER] pressed events to call url_activate_cb.
I can't find how to generate the event, however.  Any help would really be
appreciated.

Thanks!
