I thought I'd share this useful transformation. It replaces all - or _ with a space and makes the first character uppercase.

<label for="${1:some_field}"><?php echo _("${3:${1/(^[^-_]+)?([-_]+)?/(? 1:\u$1)(?2: )/g}}"); ?></label>

...would generate something like...

<label for="funky_monkey"><?php echo _("Funky monkey"); ?></label>
