XF 1.5 How to change Phrases only in specific Forum Nodes?

[XFuser]

Hello,

How do you change phrases such as "Post Reply" and "Create Thread" only within specific Forum Nodes instead of across the entire site?

You would have to edit the templates and use conditional statements utilising the node ID.

Thank you. So, for example, for the "Post Reply" phrase, how would that be done to change the "Post Reply" to "Post Your Guess" in Nodes 2, 7, and 27?

Presumably, the following line of the "quick_reply" template would need to be edited:

<input type="submit" class="button primary" value="{xen:phrase post_reply}" accesskey="s" />

But how would the conditional if for Nodes 2, 7, and 27 be done in that line?
