Usage

First, define an action. The action needs to implement IUndoableAction:

public class MyAction : IUndoableAction
{
    public string Name
    {
        get { return "My Action"; }
    }

    public void Execute()
    {
        // Do something
    }

    public void Undo()
    {
        // Put it back
    }
}

Then execute the action:

var undoRedoManager = IoC.Get<IShell>().ActiveItem.UndoRedoManager;
undoRedoManager.ExecuteAction(new MyAction());

Now the action will be shown in the history tool window. If you are using the Undo or Redo menu items or toolbar buttons, they will also react appropriately to the action.
