The command to go to the first slide in a presentation is Ctrl + Home. This keyboard shortcut is a standard feature in many presentation software programs.
Step-by-step explanation:
To move to the first slide in your presentation, you should use the command Ctrl + Home. This keyboard shortcut is a quick way to navigate to the beginning of your presentation slides in most slide presentation software such as Microsoft PowerPoint, Slides, or similar programs. Options such as Ctrl + End, Page Up, or the Next slide button serve different navigation purposes. For example, Ctrl + End typically takes you to the last slide, Page Up moves one slide back, and the Next slide button will take you to the following slide in sequence.
