Command Shortcut text string format

Question

I want to set my button tooltip by showing its shortcut key command.

<Button Command="Cut" 
            CommandTarget="{Binding ElementName=textBox}"
            Content="{Binding RelativeSource={RelativeSource Self},Path=Command}"
            ToolTip="{Binding RelativeSource={RelativeSource Self}, Path=Command.InputGestures[0]}"/>

But, it shows the result:

It shows "Ctrl+X, Ctrl+X". I just want only a "Ctrl+X". Please help me. I am the beginner.

I just found the easy way here.

<Button Command="Cut"
            DockPanel.Dock="Top"
            CommandTarget="{Binding ElementName=textBox}"
            Content="{Binding RelativeSource={RelativeSource Self},Path=Command}"
            ToolTip="{Binding RelativeSource={RelativeSource Self}, Path=Command.InputGestures[0].DisplayString}" />
