Slides and builds¶

The Slide menu adds, duplicates, deletes, hides and reorders slides, and adds builds. Every one of these commands edits the deck's code and order.txt, and can be undone.

Add a slide¶

Choose Slide ▸ New Slide and a layout, or click New Slide in the toolbar (its arrow menu shows the layouts). The new slide is added after the current one.

Layout	Contents
Title Slide	A title and a subtitle
Title and Content (`⇧⌘N`)	A title and a bulleted content box
Two Content	A title and two content boxes side by side
Title Only	A title
Blank	Nothing

Empty placeholders show prompts such as Click to add title in the editor only; nothing is drawn on the slide until you type into one. Click a placeholder to type into it. It becomes an ordinary text object in a fixed-size frame, in the deck theme's font and colour. A slide's name is its Python class name, which Manimble chooses when it creates the slide.

Add a build¶

A build is a step of a slide that waits for a click. Choose Slide ▸ New Build, or click New Build in the toolbar, to add a build after the one on screen. The new build starts out showing everything the current build shows. Manimble switches to it, so what you insert next appears at that step.

To step between builds, click them in the navigator, or use Slide ▸ Previous Build (⌘[) and Slide ▸ Next Build (⌘]).

To delete a build, click it in the navigator and press ⌫. In the code, builds are separated by self.next_slide() calls; a new build is a self.next_slide() followed by a short self.wait(), since Manim Slides skips a build in which nothing happens.

Duplicate, delete and hide slides¶

Command	Shortcut	What it does
Slide ▸ Duplicate Slide	`⌘D`	Copies the slide's class under a new name and adds it after the original.
Slide ▸ Delete Slide	`⇧⌘⌫`	Removes the slide. Pressing `⌫` in the navigator does the same. `⌘Z` brings it back.
Slide ▸ Hide Slide	`⇧⌘H`	Keeps the slide in the deck but leaves it out of presentations and exports. Choose it again to unhide.

A hidden slide stays in the navigator, dimmed and with its number struck through. It is skipped by the slideshow, Presenter View, and the PDF, PowerPoint, Keynote and movie exports. In the code it is a # manimble hidden comment on the class line.

Reorder slides¶

Drag a slide up or down in the navigator.
Or choose Slide ▸ Move Slide Up (⌥⌘↑) or Slide ▸ Move Slide Down (⌥⌘↓).

The order is saved in order.txt.

Unused slides¶

A slide class that isn't listed in order.txt is an unused slide: it is in the deck's code but not in the show. This happens when a deck keeps spare or old slides. Choose View ▸ Show Unused Slides to list them at the end of the navigator. Select one and choose Slide ▸ Restore Slide to Show (also in its right-click menu) to add it to the end of the show, then move it into place.

Navigate¶

Command	Shortcut
Slide ▸ Previous Slide	`⌘↑`
Slide ▸ Next Slide	`⌘↓`
Slide ▸ Previous Build	`⌘[`
Slide ▸ Next Build	`⌘]`

Expand All in the toolbar lists the builds of every slide in the navigator, not just the current one; click it again (Collapse All) to fold them away.

Decks with their own slide lists

New and duplicated slides are added to order.txt only. If your deck keeps its own list of slides elsewhere, for example in a build script or a progress bar drawn on every slide, update that list by hand.
