File templates manual?

In PhpStorm i can create file templates and create new files out of them. It's nice feature. However, i wonder if there are more functionality under that feature.

- Where can i find a list of all auto-variables for file template?
- Are there any string formatters or other dynamic functions i can use inside a template? (i.e. i want name of the class to be capitalized, while name of the file staying in lower case)
