I know you just press the right arrow to get auto-complete on the hardware keyboard, but I cant figure out how to make it complete on the virtual keyboard, and I prefer it to the hardware one.

Anyone know?

You click on the word when it suggests it.

If your asking how to turn it on or off I dont have that answer yet.

Odd it works for me, I'm doing it now....

I've found that's its pretty damn useless with a qwerty keyboard. By the time you look up to see what its suggesting you could have just finished typing that word.

Still, nice to have options.

Really?.... you just click on the word. Ok thanks I'll try it.

Only click on the highlighted (blue) section, otherwise you lose the completion.

would be nicer if there was a way to change the word too while typing

Since I searched a lot to reach this post and get the solution, I am adding some keywords in my submission to help other users.
