Adding hotkeys to labels in WPF forms

Earlier today I was chatting with jfo about adding hotkeys to labels and moving focus to a textbox.

<Label Target="{Binding ElementName=textBox1}"
    Width="Auto" Height="Auto" Name="label1">
    _First name:
</Label>
<Label Target="{Binding ElementName=textBox2}"
    Width="Auto" Height="Auto" Name="label2">
    _Last name:
</Label>
<TextBox Width="Auto" Height="Auto" Name="textBox1"></TextBox>
<TextBox Width="Auto" Height="Auto" Name="textBox2"></TextBox>

Underscores in the label text chooses what character is hot for that label.  Pressing alt will show the character underlined if it is not always in your windows configuration. 

Target="{Binding ElementName=textBox2}"

Tells the label where to move the focus when the hotkey is pressed.

Here is the resulting app:
