Fastest Method for Specific Slide Access:
In PowerPoint's Slide Show view, the most efficient way to jump directly to a particular slide is by typing its slide number.
Once you have typed the desired slide number, simply press the Enter key.
Alternative Navigation Methods (Less Direct):
Arrow Keys: Use the left/right arrow keys to move to the previous or next slide, respectively.
Page Up/Page Down: These keys navigate one slide backward or forward.
'G' Key: Pressing the 'G' key during a slide show brings up the Slide Sorter view, allowing you to visually select a slide.
'Ctrl + S' Shortcut: This shortcut opens the See All Slides menu, displaying thumbnails of all slides for selection.
