Shortcut to open the Goto window in file open/save dialogues WITH the equivalent to path added
You just have to delete the automatically added / in the beginning. The Go To box works from the current directory in the background.

For example if I open my home folder and press /, the Go To box opens with a / already there. If I want to work from the current directory (./), i.e., home, I just have to delete that /.

Now, if I type ./Desktop and press enter, or just Desktop and press enter, the result would be the same.
