How do I expand the full relative path of a file in file picker?

[theowenyoung]

My file hierarchy is very long, I can't see the full file path in file picker, how do I expand the full path?

[David-Else]

ctrl-t toggles the preview off so you can see much more, does that do it?

[theowenyoung]

yes, much better, but it is still not enough to show the full path...
