Code:
on ^*:hotlink:*:*:{
  if ($mouse.key & 2) {
    ;ctrl key pressed
    if ($mouse.key & 1) {
      ;left mouse click
      echo -st You have clicked on this word $+(',$1,')
    }
    return
  }
  halt
}


* there is the chance the mouse well not have turned to a pointy finger yet, if u pushed the ctrl key without moving the mouse and then clicked the mouse on a word with no mouse movement, but i would hazzard a guess thats what you want anyway. As soon as u move the mouse with ctrl down, it well show as a pointing finger.
