RubyEval in SublimeText2

From the link: https://github.com/jugyo/SublimeRubyEval and
http://kevinthompson.info/blog/2013/02/07/execute-ruby-code-inside-of-sublime-text.html.

I got a good link to run the code in the editor itself like `IRB`. I
have installed "RubyEval" using the ST2 package manger. Now can't
understand how to run the code?

what is `super+k` command? I don't understand what's the hot key to run
the code?

can anyone help me for the same?

Super is Command-key on Mac and Win-key on PC.

Additionally, verify if you have in Keys Preferences something like that: { “keys”: [“super+k”],“command”: “ruby_eval”}

with `super+k`.
