Title says it all. I found some posts linking to some private locations (mostly dead). I wonder if there ain't something like that for Safari. Google Chrome has several of them. E.g. Web Search Navigator. Are these extensions just well hidden or aren't there any at all?
I am also very annoyed by this. I found an old extension that isn't supported anymore called Mafuyu (http://wakabamac.blog95.fc2.com/blog-entry-1013.html). I've tried to run it but it's obsolete.
Another option seemed to be knogs which I found on GitHub (https://github.com/nqzero/knogs), originally for Chrome and Firefox but apparently someone adapted it for Safari. However, I have been unable to find the version for Safari because the only link i found was broken. (https://dl.dropbox.com/u/90126/GoogleJK/GoogleJK.safariextz)
If someone found the solution to this it would be greatly appreciated.
Thanks in advance.
