Answer 1

I suppose you are working on a win-form. Register a key down event:

private void Form1_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Tab && e.Shift)
    {
        // act like a backspace is pressed
    }
    else if (e.KeyCode == Keys.Back)
    { 
       SendKeys.Send("+{TAB}");   // simualte a shift-tab press
    }
}

To resolve the issue @liggett78 mentioned in the comment, you can set

form.KeyPreview = true;

to handle all the key events of child controls in the KeyDown event of the from.

EDIT: To prevent deleting a character in textbox when pressing BACKSPACE, you can:

private void Form1_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Back)
    {
        e.SuppressKeyPress = true;
        SendKeys.Send("+{TAB}"); 
    }
}

Answer 2

Override ProcessDialogKey or ProcessTabKey on your form.
