Event and Forum Topic Variable Names for Custom Teaser View Layouts

I'm trying to theme my own teaser view layouts for event and forum topic node types. Here is where I learned how to do it: http://drupal.org/node/93311

Can someone point me to where I look to see what the field values are for event and forum topic nodes? That is to say, what are the variable names to use in my theme layout for things like Start Date, End Date, Body, etc...?

Thanks!
