Last post Tool Tip

[lurch_cr]

Morning all,

A little hack we had on our old forum was a post preview in a 'tool tip' of the last post.

ie:
Last post: %date%
by %user% *arrow icon*

However when you hovered over the Arrow icon it would give you a preview of the latest post.
Similar to the standard functionality of when you hover over the title of the thread and it gives you a preview of the first post.

ANy ideas on where to start?
I found the template: forumhome_lastpostby which I guess is the place to start. And I assume I have to replace alt="{vb:rawphrase go_to_last_post} with something, but I dont know what.

Cheers all,
Lurch
