I could not resist ;-)
Rev allows many ways to script:
Here is the same as the above using a function.
What is interesting is that a function returns a value immediately  
when a condition matches and avoids using nested conditional  
structures or long statements with and/or.

on mouseDown pButton
   if PopupAllowed(pButton) then popup btn "contextualMenu" --
end mouseDown
------------------------------
function PopupAllowed pButton
   if pButton <> 3 then return false
   if word 1 of the target <> "field" then return false
   if the lockText of the target then return false
   return true
end PopupAllowed

Best regards from Paris,
