So you're diving through folders, looking for some files or data. Of course you're using Nautilus since you're running GNU/Linux and Gnome*. You get to your file, "ah ha, you found it" only to realize that you really wish you had a command line to slice and dice the file. What you'd love is to be able to just "open a terminal here". I just had that experience, and like usual (thanks to the long tail), someone else has already done this. If you're using Ubuntu (or possibly Debian) you can simply 'apt-get install nautilus-open-terminal'. Enjoy!
* No offense implied to anyone else, I'm just being silly.
