I switched from the BlackBerry to the Treo 300 recently and have been searching for a way to do a couple of my favorite BlackBerry email typing functions on the Treo:

1. Pressing the space bar twice generates a period "." and the next letter is capitalized.

2. Holding down a letter produces a capital of that letter.

3. After pressing the enter (or new line) key, the first letter on the next line is capitalized.

Anyone know if there is a hack or other way to do these things?

Thanks!
