# Interactivity properties

These properties determine **how an interactive button responds to user actions**, including clicks, key combinations, and more.

***

### **Hotkey**

Define a **keyboard shortcut** to activate the button:

* **Hotkey Setup**:
  * Use the button on the right to open **Advanced Settings**.
  * In Advanced Settings, you can:
    * Manually enter any key combination using **ASCII values**.
    * Use **Auto Detect** to automatically capture the key combination when typed.

⚙️ **Note on ASCII and Key Codes**:

* **ASCII values** distinguish between lowercase and uppercase (e.g., `65 = 'A'`, `97 = 'a'`).
* **Key codes** do not differentiate between cases. To use 'A', specify ASCII `65` and add `[Shift]` if uppercase is needed.

***

### **Page Action**

Choose a **single page-related action** (one allowed per button):

| **Option**                      | **Description**                                          |
| ------------------------------- | -------------------------------------------------------- |
| **Go to Previous Page**         | Go to the previous visible page.                         |
| **Go to Next Page**             | Go to the next visible page.                             |
| **First Page**                  | Go to the first page.                                    |
| **Last Page**                   | Go to the last page.                                     |
| **Go to Page...**               | Jump to a specific page (makes invisible pages visible). |
| **Show data sort dialog box**   | User sets sort order for a data provider.                |
| **Show data filter dialog box** | User sets a filter for a data provider.                  |
| **Exit application**            | Close the PADS Viewer application.                       |

***

### **Actions**

Add **one or multiple actions** to be executed when the button is clicked or hotkey pressed.\
Actions are executed in the order they are added.

| **Action Option**                                     | **Description**                                                                            |
| ----------------------------------------------------- | ------------------------------------------------------------------------------------------ |
| **Send Web Request command**                          | Send HTTP request (GET, POST, PUT, PATCH, DELETE) and optionally switch pages.             |
| **Edit Viewer Variable**                              | Change or reset a Viewer Variable value until presentation ends.                           |
| **Scroll data (up/down/page up/page down/begin/end)** | Scroll a data provider in various ways. *Note: Resets on page change.*                     |
| **Set data filter (with page change)**                | Apply a dynamic filter to a data provider and optionally switch pages.                     |
| **Clear data filter (with page change)**              | Clear previously applied dynamic filters.                                                  |
| **Apply data sort for this page**                     | Sort data provider's data. Resets when page changes.                                       |
| **Apply data filter for this page**                   | Apply a page-specific filter. Resets when page changes.                                    |
| **Send message to Web Element**                       | Control a Web Element (toggle microphone/camera, join/leave meeting, send custom command). |
| **Open webpage in external window**                   | Open URL in a separate browser window.                                                     |

### **Important Notes on Scrolling and Filters**

* **Scrolling with interactive buttons** can conflict with **automatic scrolling** — may cause double scrolling.
* **Filters and sorts** applied via buttons **reset on page change**, unless noted (e.g., dynamic filters stay active until cleared).
* When **scrolling or filtering data**, ensure that the interactive button targets the **same data provider** used by page elements.

***

### **Special Remarks**

* **Synchronize Mode**: If **presentation synchronization** is enabled, **interactive features (e.g., page navigation)** will **not function** to maintain sync.
* **Hotkey Configuration**:
  * **ASCII value** is case-sensitive.
  * **Key code** is not case-sensitive.
  * Use Auto Detect for easy hotkey setup.
