How to shift focus from one text box to another?

[TheIndependentAquarius]

The code creates two input text boxes:

import QtQuick 1.0
 
Column 
{
  width: 500
  height: 200
 
  Text 
  {
    id: userInfoTextA
    focus: false
    text: "Enter a value from 0 to 10:"
  }
 
  TextInput
  {
    id: userInputA
    focus: true
 
    anchors.left : userInfoTextA.right
    anchors.leftMargin : 20
 
    validator: IntValidator { bottom:0; top: 20 }
 
    Keys.onReturnPressed: 
    {
      console.log (userInputA.text)
    }
  }
 
  Text 
  {
    id: userInfoTextB
    focus: false
    text: "Enter a value from 10 to 20:"
  }
 
  TextInput
  {
    id: userInputB
    focus: true
 
    anchors.left : userInfoTextB.right
    anchors.leftMargin : 20
 
    validator: IntValidator { bottom:0; top: 20 }
 
    Keys.onReturnPressed: 
    {
      console.log (userInputB.text)
    }
  }
}

import QtQuick 1.0

Column 
{
  width: 500
  height: 200
  
  Text 
  {
    id: userInfoTextA
    focus: false
    text: "Enter a value from 0 to 10:"
  }
  
  TextInput
  {
    id: userInputA
    focus: true
    
    anchors.left : userInfoTextA.right
    anchors.leftMargin : 20
    
    validator: IntValidator { bottom:0; top: 20 }
    
    Keys.onReturnPressed: 
    {
      console.log (userInputA.text)
    }
  }
  
  Text 
  {
    id: userInfoTextB
    focus: false
    text: "Enter a value from 10 to 20:"
  }
  
  TextInput
  {
    id: userInputB
    focus: true
    
    anchors.left : userInfoTextB.right
    anchors.leftMargin : 20
    
    validator: IntValidator { bottom:0; top: 20 }
    
    Keys.onReturnPressed: 
    {
      console.log (userInputB.text)
    }
  }
}

To copy to clipboard, switch view to plain text mode 

In the output window the focus, by default, is set to the text box A. How should I move the focus to text box B by:
- Keyboard

and

- Mouse
?

From stackoverflow I came to know about key navigation for shifting focus through keyboard:
