Plan several routes at once
Planning a journey with multiple destinations can quickly become disorganized. It you want to plan where to visit while on vacation, for example, it helps to have several tabs open to keep track of your options.
To do this, press Cmd+T to open a new tab, or use Cmd+N for a window. If you have several windows open at the same time, you can merge them into tabs in one window by choosing Window > Merge All Windows.
