Assert.False(checkNone);
var none = ModifierKeys.None;
checkNone = none == ModifierKeys.None;
Assert.True(checkNone);

Definition: ModifierKeys.cs:31

An example usage is:

var ctrl = ModifierKeys.Ctrl;
var alt = ModifierKeys.Alt;
var ctrlAlt = ctrl | alt;
bool isNone = ctrlAlt == ModifierKeys.None;
bool isAlt = ctrlAlt.HasFlag(ModifierKeys.Alt);
bool isCtrlAlt = ctrlAlt == (ModifierKeys.Alt | ModifierKeys.Ctrl);
