[TxMt] building snippets?

I'm trying to learn about writing useful snippets for things I do often. It looks like I need some conceptual help. For example, I use this snippet:

<tr>

<td><cite>${1:title}</cite></td>
<td>${2:composer}<br />
arr:${3:arranger}</td>

</tr> </table>$0

with a tab trigger of </table>

already helps a lot when building tables of works performed. It nicely gets rid of the ending </table> and inserts another set when I press tab at the end of the snippet.

That worked so well I got greedy. I'd like to cause the snippet to force the title be Title Case.

A second interest is an easy way to get rid of the break and the arranger when the piece doesn't have one without killing the ability to use a tab trigger at the end. I can use lots of deletes. Is there a better way.

Fascinating tool, TextMate.
