It shouldn't be too hard. Just use $read() to find the item, then calculate $readn - 2 (this gets you to line 1 in the item list for the selected item). Then, just increment the read line until you've set variables for everything in the item and display via msg.
If no one else wants to help out, I might be able to later on. It really isn't a difficult script. You could probably do it yourself if you know anything about scripting.
/help on text
/help $read
/help $readn
/help $calc
/help if then else
/help /msg
/help /var
/help /inc
That pretty much covers everything you might need to complete the script.
