```
KeyBinding keyBinding = new KeyBinding
{
    Key = Key.Asterisk,
    Modifiers = ModifierKeys.None,
    Command = YourCommand
};

this.InputBindings.Add(keyBinding);
```
```
xmlns:Input="clr-namespace:System.Windows.Input;assembly=PresentationCore"
```
In order to use the asterisk (*) key as a hotkey in a WPF application, you can use the KeyBinding class in XAML or programmatically in your code-behind. Here's an example of how to bind the asterisk key to a command using XAML:
1. Declare the namespace for the Input class in your XAML file:
2. Make sure to replace YourCommand with the command you want to bind to the asterisk key. The Modifiers property is set to None to bind the asterisk key without any modifier keys.
This will bind the asterisk key to the specified command, and whenever the asterisk key is pressed, the command will be executed.

Alternatively, if you prefer to set the binding programmatically in your code-behind, you can do it like this:

In WPF, you can bind a key to a command using the KeyBinding class. However, the asterisk () key is a bit tricky because it’s usually associated with the Shift modifier (Shift + 8 on a standard keyboard). Here’s an example of how you can bind the asterisk () key to a command:
```
    
```
In this example, YourCommand is the command that will be executed when the user presses Shift + 8 (which is equivalent to * on a standard keyboard). You would replace YourCommand with the actual command you want to bind to the asterisk (*) key1.

Please note that this will only work if the focus is on the window or a child control that does not handle the Shift + 8 key combination itself. If you want to ensure that the key binding works regardless of which control has the focus, you might need to handle this at a higher level, such as by using a keyboard hook2.

Remember to replace YourCommand with the actual command in your ViewModel that you want to execute when the key combination is pressed. The command should be a public property in your ViewModel and should implement the ICommand interface.
