In the webos 2.1, should be Option+spacebar to bring smily face menu in messages app, but after you used option key one time, the spacebar will bring smily face menu, do not need an option key. It cause some problem, you can not input space in your message. And in chinese input, we use spacebar to choose words. I tried "smiley faces in symbol box reversed" patch, but the problem still there.
Anyone can give some suggestion?
