reproduce:
open the new 2.6 file chooser in "open" mode
100% reproduceable

description:
First, pressing CTRL-L is to bring up the "open location" dialog is completely
undiscoverable.  There is nothing in the dialog that indicates that this
capability exists.  This by itself, indicates a break with 20+ years of GUI
development, and leaves users of ALL GUIs confused and frustrated.

Second, user is presented with a dialog in a dialog, which many consider to be
bad form.  What's worse, is that the "open location" dialog only allows
directories to be specified.  Specifing the entire path to the file results in
the main dialog simply changing to the directory the file is located in.  (i.e.
Saying "open location: /etc/passwd" will cause the main open dialog to be set to
"/etc".)

fix:
Eliminate the "open location" dialog, and fold its capabaility back into the
main dialog.
