How do I trigger Emmet expansion in Netbeans?

You can expand code using the default "ctrl+cmd+N" on a mac.

I came across this question trying to find out if there was anyway that I could configure the code expansion to trigger by just using the "tab" key.

Anyways, I hope this helps someone!

I am using netbeans ver 8.1 in ubuntu 15.10. After selecting your CSS code,use ctrl+alt+n to trigger emmet code completion.
