I mean by not having to press ctrl-E though. Not sure why it is locked until ctrl-E is pressed?
It is not locked (?) it is not a edit field since it is a crumbbar.. you can click and right click on path item to go to them or get a list of subpaths to go there
If you double click there you enter edit mode.. But if you are just pasting a path. There is no need to do that there,.,
And as espkk said.. You can also enter the path in the command line field to go to that field
