How do you use the "predictive" text input feature on a Samsung M360?

Okay, so I’m trying to figure out texting on my new phone. I had a Motorola with iTap for a few years and was super excited to go back to a phone with the t9 text input feature, and I thought I read somewhere that this phone, a Samsung M360, had it. Turns out its “predictive” input is slightly different, but so far, I still think it’s better than iTap.

So here’s my question:
When you type in a word, the little drop-down menu appears below it with other word options. I can navigate that fine by using the down arrow and clicking “ok” when I’m on the word I want, but you can also use the “0” to scroll down…so is there any other way you can select an alternate word, besides hitting “ok?” I want to be able to just scroll down to it and hit “space,” or the pound key (I vaguely remember that’s how it worked with t9), to select it and move on to the next word, but I can’t get that to work. Does anyone know if it’s possible to enable such a setting? Thanks a bunch!
