Definition

Namespace:
System.Windows.Input
Assembly:
WindowsBase.dll

Specifies the set of modifier keys.

This enumeration supports a bitwise combination of its member values.

public enum class ModifierKeys
[System.ComponentModel.TypeConverter(typeof(System.Windows.Input.ModifierKeysConverter))]

public enum ModifierKeys
[<System.ComponentModel.TypeConverter(typeof(System.Windows.Input.ModifierKeysConverter))>]

Alt 1

The ALT key.
Control 2

The CTRL key.
Shift 4

Examples

The following example shows how to create a KeyBinding that associates a KeyGesture with a RoutedCommand. The KeyBinding uses the ModifierKeys enumeration to specify the modifier key of the gesture.

<Window.InputBindings>
  <KeyBinding Command="ApplicationCommands.Open"
              Gesture="CTRL+R" />
</Window.InputBindings>

// Creating a KeyBinding between the Open command and Ctrl-R
KeyBinding OpenCmdKeyBinding = new KeyBinding(
    ApplicationCommands.Open, 
    Key.R, 
    ModifierKeys.Control);

this.InputBindings.Add(OpenCmdKeyBinding);

' Creating a KeyBinding between the Open command and Ctrl-R
Dim OpenCmdKeyBinding As New KeyBinding(ApplicationCommands.Open, Key.R, ModifierKeys.Control)

Me.InputBindings.Add(OpenCmdKeyBinding)

Remarks

The Modifiers property on the Keyboard class is the set of the modifier keys that are currently pressed.

Some APIs in Windows Presentation Foundation (WPF) that make use of the ModifierKeys enumeration are the Modifiers properties on the Keyboard, KeyBinding, KeyGesture, and MouseGesture classes.
