# Page turning and viewer tools > Fine-tune how pages turn, and choose which tools shoppers can use in the viewer. Source: https://docs.neoflipbook.com/customize/page-turn-and-tools/ App: Neo Product Catalog Flipbook Last updated: 2026-10-01 The **Behaviour** tab controls how pages move as they turn and which tools appear in the viewer. In Neo Product Catalog Flipbook, go to **Flipbooks**, click the flipbook’s title, then click the **Behaviour** tab. Make your changes, watch a page turn in the preview, then click **Save**. ## Page turn speed **Page turn speed (ms)** is how long one page turn takes, in milliseconds. The default is 700 (0.7 seconds), and you can enter 0 to 5000. A lower number turns pages faster. For pages that change instantly, choose **No animation** as the flip style on the **General** tab instead. See [Title, flip style and start page](https://docs.neoflipbook.com/customize/general-settings/). ## Easing **Easing** is the motion curve of a page turn: whether the page moves at a steady pace, or speeds up and slows down along the way. The default is **easeOutCubic**. | Option | How the page moves | | -------------------------------------------------- | ------------------------------------------------------------------------------------------ | | **linear** | At the same speed from start to finish. | | **ease** | Starts gently, speeds up, then slows at the end. | | **easeInQuad** | Starts slowly and speeds up. | | **easeOutQuad**, **easeOutCubic**, **easeOutExpo** | Starts fast and slows down as it lands. Quad slows down the least and Expo the most. | | **easeInOutQuad**, **easeInOutCubic** | Starts and ends slowly, and moves fastest in the middle. Cubic is the stronger of the two. | | **easeOutBounce** | Bounces a little as it lands. | | **easeOutElastic** | Overshoots, then springs back into place. | ## Page shape and depth | Setting | Range | Default | What it changes | | ------------------ | ------- | ------- | ----------------------------------------------------------------------------------------------- | | **Curl** | 0 to 1 | 0.8 | How far the page bends as it turns. | | **Shadow** | 0 to 1 | 0.7 | How dark the shadow is as a page turns. | | **Elasticity** | 0 to 1 | 0.5 | How springy the page feels as it settles into place. | | **Peek** | 0 to 1 | 0.6 | How far a page corner lifts when a shopper points at it with a mouse. Enter 0 to turn this off. | | **Page thickness** | 0 to 20 | 1.5 | How thick the stack of pages looks. | **Curl**, **Shadow**, **Elasticity** and **Peek** change in steps of 0.1, and **Page thickness** in steps of 0.5. If you enter a number outside the range, the app saves the nearest allowed value. These settings shape the default **WebGL 3D page rendering** style. With other flip styles, most of them have little or no visible effect. ## Viewer tools Under **Features**, tick the tools shoppers can use. All of them are on by default except **Page turn sound**. | Tool | What shoppers can do | | ---------------------- | -------------------------------------------------------------------------------------------------------------- | | **Zoom** | Zoom in and out of pages. | | **Fullscreen** | Fill the whole screen with the flipbook. | | **Thumbnails** | Open a panel of small page previews and jump to any page. | | **Search** | Search for words in a PDF or a product catalog. Not available for image flipbooks. | | **Bookmarks** | Mark pages to come back to later. | | **Page indicator** | See which page they’re on. | | **Outline** | Open the PDF’s own table of contents, if the PDF has one. | | **Links** | Click links inside your PDF, and click product cards in a catalog. | | **Print** | Print pages. | | **Download** | Download the original PDF file of a PDF flipbook. | | **Share** | Share a link to the flipbook. | | **Page turn sound** | Hear a soft paper sound as pages turn. | | **Keyboard shortcuts** | Turn pages with the arrow keys or Page Up and Page Down, and jump to the first or last page with Home and End. | > **Keep Links on for catalogs** > > In a product catalog, the **Links** tool is what makes product cards clickable. If you turn it off, shoppers can’t open a product from its card. ## Related pages - [Toolbar and navigation buttons](https://docs.neoflipbook.com/customize/toolbar/) - [What shoppers see](https://docs.neoflipbook.com/storefront/what-shoppers-see/)
