Component Help

I can't seem to be able to find this anywhere in the community although I know that someone here knows how to do this, I somehow never had a permanent link button on my entries and now I realize I really need one.

Can anyone point me in the direction to where I could find this or what I need to put in my stylesheet?

I tried using set text_permalink = "Link"; but it isn't changing. Any ideas?

Thanks in advance.
