# Zoom and Navigate

> Steps the timeline between three track heights and a clip's editor, zooms in time, and moves the cursor from the keyboard. Press ⌥↑ and ⌥↓ to change the height, ⌥2 to fit the whole song.

## Change the track height

<video src="/videos/timeline-zoom.mp4" poster="/videos/timeline-zoom.jpg" aria-label="Option up packs the tracks into Compact rows, Option down brings back Normal, Option 2 fits the whole song" title="Option up packs the tracks into Compact rows, Option down brings back Normal, Option 2 fits the whole song" muted loop playsInline preload="none" />

Press `⌥↑` for **Compact** tracks and `⌥↓` for **Normal**. With nothing selected, `⌥→` and `⌥←` zoom in and out; `⌥2` fits the whole project.

## Zoom into a clip

<video src="/videos/timeline-focus.mp4" poster="/videos/timeline-focus.jpg" aria-label="Option down opens the Reese bass clip as a piano roll right in the timeline, Option up steps back out" title="Option down opens the Reese bass clip as a piano roll right in the timeline, Option up steps back out" muted loop playsInline preload="none" />

Select a clip and press `⌥↓` at Normal height. It opens in [Focus Mode](/edit/focus-mode.md) right inside the timeline. `⌥↑` steps back out.

## Zoom in time

With nothing selected, press `⌥→` to zoom in and `⌥←` to zoom out. Or hold `⌥` and scroll, which zooms around the pointer.

## Fit the selection or the whole song

Press `⌥1` (**Zoom to Selection**) to fit the selected clips or the marked range, and `⌥2` (**Zoom to Project**) to fit the whole song.

## Move the cursor from the keyboard

Press `→` / `←` to move the edit cursor one grid step and `↑` / `↓` to move it to the track above or below. `Fn←` / `Fn→` (`Home` / `End`) move it four grid steps.

## Good to know

* **`⌥↓` and `⌥↑` walk one ladder, a rung per press**: Compact rows → Normal rows → Focus Mode → the focused MIDI clip's piano roll at full window height. **Normal** is the default.
* **Track height has fixed sizes instead of a free zoom**, so you never adjust heights to see what you need.
* **With clips selected or a range marked, `⌥→` and `⌥←` move them a fine step instead of zooming.** `Escape` lets go of the selection and gives the keys back to zoom and the cursor.
* **The grid follows the zoom.** Zoom in and the grid lines, and so the arrow-key steps, get finer.
* **To jump between song parts, use [locators](/arrange/loop-and-locators.md).** Where the cursor and playhead differ: [Cursor, Playhead and Loop](/get-started/cursor-playhead-loop.md).

> **Details**
>
> * **Sample and automation clips stop one rung short of the piano roll.** Their editor is a fixed shallow band, so there is no extra height to reveal.
> * **`⌥↓` is Enter Focus Mode and `⌥↑` is Exit Focus Mode** in the Command Palette, whichever rung you are on.
> * **With content marked, `Fn←` / `Fn→` move it a bar** instead of moving the cursor (**Big Step Left** / **Big Step Right**).
> * **Scroll moves the timeline sideways; `⇧`-scroll moves it up and down.**
> * **Hold `⌥` and drag vertically to zoom**, with the point under the pointer held still. Drag horizontally to scroll.
> * **`⌥1` with nothing selected does nothing.** Select clips or mark a range first.
