title: Block Normal Key Function
body: <p>I am binding a normal key do run a function using Tkinter, like this:</p>
  
  <pre><code>from tkinter import *
  root = Tk()
  T = Text()
  T.pack()
  root.bind_all('h', lambda event: print('HI'))
  </code></pre>
  
  <p>When you press the <code>h</code> key, it prints <code>HI</code>, but also it types an <code>h</code> into the text box. Is there any easy way to block the <code>h</code> key from doing its normal purpose?</p>
