title: How to get Tkinter Mac-friendly menu shortcuts (cmd+key)
body: <p>I am considering shortcuts for Tkinter menu labels (commands).
  On Macs the combination with cmd ⌘ is common. </p>
  
  <p>So far I have found only <code>self.bind_all("&lt;Control-q&gt;", self.quit)</code>. How to implement cmd ⌘ shortcuts?</p>
  
  <p>Then again, thinking about - once the app is finished - translating it to an executable file for Windows and a Mac application might cause difficulties when using cmd ⌘?
  What is the best way of dealing with this issue?</p>
