How to kick people using chat commands?

[Uesegi]

I've seen other servers kick people just using the chat command (or using Ctrl + A), and I'm unsure how to perform this. It would go like this for example:

/kick playername
/k playername

Is this an add-on? Or is it a console command or some sort?

Its a addon, look for it on forums.
