I can't remember where I got this, but it should do the trick. Been
using it for ages.

<h2 id="${1/[[:alpha:]]+|( )/(?1:_:\L$0)/g}">${1:$TM_SELECTED_TEXT}</h2>

* * *

This snippet uses a placeholder:

    ${1:placeholder-text}

This snippet mirrors what you type in another place:

   ${1:Hello}
   #1 gets mirrored here: $1
   ${2:Type something else here}
   and #2 gets mirrored here: $2

This snippet replaces spaces with underscores:

   ${1:Text with spaces}
   Mirrored with transformations: ${1/( )/_/g}

Hope this helps clear things up.
