Modifiers

[Apostolique]

In some cases, some keys shouldn't trigger Pressed or Released. For example: CTRL + A.

If we're currently holding A, then pressing CTRL shouldn't trigger a CTRL + A press.

ICondition SelectAll =
    new AllCondition(
        new KeyboardCondition(Keys.LeftControl),
        new KeyboardCondition(Keys.A)
    );

In a select all CTRL is a modifier. A new class could be created handle that case:

ICondition SelectAll =
    new AllCondition(
        new Modifier(
            new KeyboardCondition(Keys.LeftControl)
        ),
        new KeyboardCondition(Keys.A)
    );

Modifier would always return false for Pressed and Released.

Note: There might be an edge case to think about. What happens if a user is currently pressing A then presses CTRL, Should that trigger Held and HeldOnly for CTRL + A? It might make some code harder to write on the user side.
