> give me a way to TYPE INTO THE BLOODY THING!
It exists. You just have to try it.
Type the name of the file to jump to the file. Keep typing to select the exact file.
Or press / to type the full path into the location dialog, seeing a drop down list of possible completions along the way.
I don't see how the sequence of key presses is much different to typing into a terminal, or the old file manager.
By the way, Nautilus has great keyboard navigation too.
