Create new apex class in Cloud9?



I’m working through a pluralsight course on salesforce apex development. The instructor is using MavensMate as an IDE for the code demos and I’m trying to translate the instructions to cloud9 equivalents.
First thing I run into is he states:
Goto MavensMate->MetaData->New apex class

from here mavensmate provides a huge list of apex related code templates from which he instructs to search for ‘test’ and choose Unit Test from the resulting search process.

What would be the Cloud9 equivalent for performing this?
