How can I switch to the Android keyboard "SMS" mode
<p>The default Messaging app in Android (tested against version 2.1) appears to put the soft keyboard in a special mode, where the return key is replaced with an "emoticon key". When you press it you get a selection of emoticons to insert into your message.</p>

<p>How do I instruct the soft keyboard to appear in this mode in my app?</p>
