How do you add nofollow code to links on landing pages?

EDIT

Based on this: http://stackoverflow.com/questions/14303689/javascript-add-rel-nofollow-on-returned-data adding nofollow via jQuery won't matter to search engines because they don't execute Javascript.

Thanks Jason, 

Sorry, the jQuery stuff is above my head. 

In the Insert/Edit Link pop-up there is a place to select the target, which inserts the target coding to the URL. The nofollow code can go adjacent to the target code, but your saying there is no way to do this with selections in the general or advanced tab of the pop-up?  It would seem if I could edit the URL for the target from this menu, there would other options to add other code to the URL.

 

There doesn't appear to be a way to add rel="nofollow" links via the TinyMCE editor; you'll have to do it manually.

That's what I was afraid of.

Thanks again,
Ed
