How to turn off or turn off footer elements on one or all slides in PowerPoint?

PowerPoint has two levels of control on footer elements: Date, Footer text, and Slide Number.

1. Layout Level - Footer elements can be added or removed on a layout. For example, if the Slide Number is added on a layout, all slides based this layout will display slide numbers in the footer area.

2. Slide Level - Footer elements can be turned on or off on one slide or all slides. For example, if the Slide Number is turned off on a slide, this slide will not display the slide number, even its layout has the slide number defined.
