title: What are the available variables in Atom editor and how can I use them?
body: <p>I'm exploring the Atom editor and trying to set up some Snippets. I would like to know if there are variables that I can use to insert things like the Author's name, file creation date, etc.</p>
  
  <p>I looked around and since Atom is patterned after Sublime, I tried to use $TM_FULLNAME but it didn't seem to work. Where might I find the variables that Atom exposes (if any)?</p>
  
  <p>Regards,</p>
