How can I make a textbox perform a backspace when I'm Not typing in it VB.NET
<p>I'm making a hex keyboard converter with two TextBoxes: TextBox1 for typing in the key you want to convert, and TextBox2 for displaying what you converted.</p>

<p>So far I have gotten it to convert as I typed, but when I press <kbd>Backspace</kbd>, TextBox1 will erase the key but TextBox2 will remain with the same converted code, meaning I have to go to TextBox2 to erase it manually.</p>

<p>Is there a way I can make it so that when I press <kbd>Backspace</kbd> while typing in TextBox1, the TextBox2 will go back as well? And is there a way I can tell it how many spaces to go back?</p>
