Final answer:
Select the Slide Sorter View to navigate to slide 4 using the thumbnails; this view shows all slides, allowing you to click directly on the thumbnail of slide 4.
Step-by-step explanation:
To navigate to slide 4 using the slides tab (thumbnails), you should select the Slide Sorter View. This view displays all slides in your presentation as thumbnails, making it easier to find and select a particular slide. When you are in the Slide Sorter View, you can click directly on the thumbnail of slide 4 to navigate to it. Alternatively, if you are currently viewing another slide in the normal editing view, you can also click on the slide thumbnails typically found on the left-hand side of the screen to switch to slide 4.
