Typing Numbers

[mpg187]

I came over to Android from Windows Mobile and hate when typing numbers you have to press an extra button. Is there a way I can have it so I only have to tap one button to type a number?

Double tapping the function button will lock it

But then when I want to type letters again it's still a pain. I prefer having letters a numbers on the same screen...
