I'd suggest to save the current word in a global variable (`defvar') and
only update the translation if the current word is not nil and not
string= with the saved word.  When that's the case, do the translation
and save the current word in the global variable.

I normally don't need that, because I use Emacs fullscreen and use this
in my ~/.emacs.

--8<---------------cut here---------------start------------->8---
(defun th-split-window (window)
  "Split WINDOW either horizontally or vertically.

If the WINDOW is wide enough, then split horizontally, else
vertically."
  (if (>= (window-width window) 150)
      (split-window window nil t)
    (split-window window)))

(setq split-window-preferred-function 'th-split-window)
--8<---------------cut here---------------end--------------->8---

So new windows will be created beside (and not below) the current one if
the current window has more than 150 columns.

The variable `split-window-preferred-function' is pretty new, so it's
possible that it won't work for you unless you use emacs 23.

Bye,
