if you take a look in the PowerUser package I provided I made a textmatetag.sublime-snippet...
basically it allows you to wrap an elemnt in a tag just exactly as it works in textmate or e-text
and for those that don't want to bother downloading the package here it is...
<!-- Insert open/close tab - textmate way -->
<binding key="ctrl+comma" command="insertSnippet 'Packages/PowerUser/Snippets/HTML/textmate_tag.sublime-snippet'">
<context name="selector" value="text.html - source, text.xml"/>
and the snippet...
the regex in the snippet makes sure that when you type a tag with attributes the attributes don't get mirrored in the closing tag... default behavior in sublime it does... not good
