Helper to check for modifier and system keys during input, with counter excluding said input.
KeyEventArgsHelper.cs file contains helpers.
A simple method to check for keyboard modifiers:
public static bool ModifierKey(KeyEventArgs e)
{
if (e.KeyboardDevice.Modifiers == ModifierKeys.None)
return false;
else
return true;
}
As well as a method to check for each system key (modifier keys are commented out in case someone wants to just use that method and uncomment the appropriate lines):
public static bool SystemKey(KeyEventArgs e)
{
switch (e.Key)
{
//case Key.LeftAlt:
// return true;
//case Key.RightAlt:
// return true;
//case Key.LeftCtrl:
// return true;
//case Key.RightCtrl:
// return true;
//case Key.LeftShift:
// return true;
//case Key.RightShift:
// return true;
//case Key.LWin:
// return true;
//case Key.RWin:
// return true;
case Key.Tab:
return true;
