As far as just a single letter calls the function, it's useless. But I really hope tto see it fixed soon, it has great potential.

Ulasan ini untuk add-on (1.4.1) versi terdahulu. 

Are you using Firefox 2 or Thunderbird 2 on Mac OS X? Otherwise, a single letter calls the function if and only if you selected text previously.
