title: Key bindings for interrupt execution in Python Sublime REPL
body: <p>I'm using REPL extension for Sublime text 3 for my python projects. Currently when I want to interrupt a running script I have to close to close the REPL window to stop execution and all computations are so far are lost. 
  I was wondering if anybody knows how to interrupt an execution and have a short cut or key bindings for that</p>
