Use of TicketFreeText'n ':: Link

[yuri0001]

Good afternoon, colleagues,
I would like to understand how to use TicketFreeText'n ':: Link.
In the documentation it was too sparingly, if not - nothing, only the format of references, and that there might be??
Share, if someone has used and understood as it usefully can tie.
An example, pls!
And how it look like on screen?

it is a dynamic link using the value as the freefield (try the example)...

It looks like a link...

Yes, it's a link and what can i do with this link? How can i use this, I don't understand it!

[jojo]

you can click it and access another web application using some dynamic data of the value of the free field
