How to assign hotkeys to execute native Sublime Text 3 plugin?

Question

Python

I'm trying to write my plugin for sublime text.
file is created:

import sublime
import sublime_plugin

class Myautotext(sublime_plugin.TextCommand):
  def run(self, edit):
    self.view.insert(edit, 0, "Hello, World!")

view.run_command('myautotext')starts with the command .
key assignment not working:
{ "keys": ["ctrl+*"], "command": "myautotext"}
