title: Tkinter: When press 'Enter', then it goes to the next text box
body: <p>So my teacher told me to learn Tkinter be myself and I try to understand it.
  Here's is the program I'm looking at.</p>
  
  <p>It asks for a name and last name. (Yeah, Spanish is my native language)</p>
  
  <p>When I finish inserting the name, I just want to press enter to go to the next text box which is last name.</p>
  
  <pre><code>from tkinter import *
  
  master = Tk()
  Label(master, text="Ingrese sus nombres: ").grid(row=0)
  Label(master, text="Ingrese sus apellidos: ").grid(row=1)
  
  e1 = Entry(master)
  e2 = Entry(master)
  
  e1.grid(row=0, column=1)
  e2.grid(row=1, column=1)
  
  mainloop()
  </code></pre>
