    <Grid> 
     <Button x:Name="btn1" Command="{StaticResource MyCommand1}" Content="Click me"     Visibility="Collapsed" />

你可能尋找OemPlus或Add鍵：

<KeyBinding Key="OemPlus" Modifiers="Ctrl" Command="{StaticResource MyCommand3}" /> 
<KeyBinding Key="Add" Modifiers="Ctrl" Command="{StaticResource MyCommand3}" />
