# Previewing promotions

> Zoom, pan, fit, search, and navigate images, PDFs, and videos in the promotion preview, and place comments from the control bar.

Every promotion opens in a preview that shares one control bar across asset types, so zooming, fitting, and commenting work the same way whether you're looking at an image, a PDF, or a video.

## The control bar

The control bar floats at the bottom-centre of the preview. It stays out of the way on a narrow window — the lower-priority controls collapse and the rest scroll — so the core zoom controls are always reachable.

| Control                | What it does                                                                                                                                                                         |
| ---------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **Zoom out / Zoom in** | Step the zoom down or up.                                                                                                                                                            |
| **Zoom level**         | Shows the current zoom as a percentage. Click it for a menu with **Fit width**, **Fit to page** (PDFs), and preset levels (50%, 100%, 150%, 200%, 400%). The active level is ticked. |
| **Fit to width**       | Scales the asset so it fills the width of the viewport.                                                                                                                              |
| **Fit to page**        | (PDFs) Fits a whole page in view.                                                                                                                                                    |
| **Reset view**         | Returns to the default zoom and recentres.                                                                                                                                           |

## Zooming and panning

Beyond the buttons, the preview responds to trackpad and mouse gestures:

* **Two-finger scroll** pans around the asset.
* **Pinch**, or **hold `Ctrl`/`⌘` while scrolling**, zooms in and out towards the pointer.

Images and PDF pages zoom up to 800%. SVGs are vector, so they zoom much further without going blurry.

## Navigating a PDF

PDFs add a sidebar (toggle it from the leftmost button on the control bar) with everything specific to multi-page documents:

* **Page controls** — type a page number to jump to it, or step through with the up/down buttons.
* **Find in document** — search the full text of the PDF. The field shows the current match position and total (e.g. `2/7`); press `Enter` for the next match, `Shift`+`Enter` for the previous, and `Esc` to clear. Matches are highlighted on the page.
* **Pages** — a thumbnail of every page; click one to jump to it.
* **Outline** — the document's bookmarks, when it has them.

## Commenting from the preview

The **Add comment** button lives on the control bar. Click it to enter comment mode, then click the asset to place your marker. You can also **show or hide** existing comments from the bar; the button carries a badge with the comment count. For the full commenting workflow, see [Comments and collaboration](/marketing/comments-collaboration).

## Downloading

When downloads are available for a promotion, the **Download** action also sits on the control bar.
