Select a slide, open Transitions, and choose None. Then select Apply to All to remove transitions throughout the presentation. If removing only the effect between two slides, select the incoming slide. Object animations are separate, so text or pictures may still animate after transitions are removed.
Open Slide Show, Set Up Slide Show and enable Show without animation. This disables animations for presenting without requiring you to remove every effect from its object. Test the presentation afterward and turn the option off when needed. Transition settings are managed separately on the Transitions tab.
Open the Animation Pane and select the object to see its effects. Choose the specific effect you want to remove and use Remove or Delete. Check the remaining sequence afterward. Selecting None for the whole object removes all its effects, which is different from deleting one animation step.
Select the objects together using Ctrl on Windows or Command on Mac, then use the shape-formatting Group command. Apply an animation to the resulting group. The group now behaves like one object during playback. Check that you included only the items intended to move or appear together.
Select the slide, open Home's Layout or Slide Layout menu, and choose a suitable layout such as Comparison. Move content into the appropriate placeholders and check the result. Layouts supply predefined content positions; they are more reliable for consistent alignment than repeatedly drawing separate text boxes by eye.
Select the slide and choose Home, Reset to restore its layout formatting. PowerPoint keeps the content you added while resetting the layout. Inspect the slide afterward, especially if you also added independent text boxes or shapes. Reset is a layout repair tool, not a command to create a blank slide.
On Windows, open Design's Variants menu, choose Colors, and then Customize Colors. Set the text, background, accent, and hyperlink colors you need, give the combination a name, and save it. Preview several slides, since changing theme colors can affect many objects that use those theme values.
Open View, Slide Master, then use Fonts and Customize Fonts to choose heading and body fonts. Name and save the combination, then inspect the presentation. Theme fonts make shared styling easier, but review text that was manually formatted or pasted from elsewhere rather than assuming every text box changed.
After adjusting the colors, fonts, and effects, choose Save Current Theme from the theme controls. Save the theme with a recognizable name; it uses a .thmx file. Apply it from the theme gallery in another presentation, or browse to its saved location if it is not listed.
Open Insert, Slide Number and enable slide numbering. Select the option not to show it on the title slide, then Apply to All. Check several slides to confirm the placement. The theme controls the normal position; use the slide master if the number needs to move consistently.
Use separate slide masters for the themes. Open View, Slide Master, and insert another master before customizing its theme and layouts. Simply replacing the theme on your only master changes that master's design. Apply layouts from the appropriate master to keep the two presentation sections visually distinct.
Open View, Slide Master and select a slide layout beneath the master. Choose Insert Placeholder, select the picture type, and draw its area. Close Master View, then reapply that layout to the affected slides. Placeholders are added to layouts rather than directly to individual slides in Normal view.
After editing the placeholder in Slide Master view, close that view and select the affected slides. Use Home, Layout to reapply the revised layout. This completes the change on those slides. Check that you edited the layout they actually use, rather than a similar layout under another master.
