Spotatube is a little script made for personal use quite long time ago, it
may or may not work - it does on my setup though.
It is supposed to be bound to some key-combination (all DM should have such option).
Personally I use Ctrl+Alt+Shift+P.
It can find links to YouTube search page and directly to first Youtube result. Link can be opened automatically and/or copied to clipboard.
spotatube is GNU GPL v2
