# Preview options

If you hover over the ▶️ button, you can see a few options. Let's go over them in a bit more detail.

### Auto-run

Tired of clicking ▶️ constantly? Enabling this option ties pressing ▶️ to your keystrokes, updating the preview area as you type. Pretty handy for larger projects, where minute detail is key.&#x20;

This is a setting you can toggle on or off entirely in the **Settings Menu**, in the **Startup Behavior** section.

### Preview&#x20;

> **Separate window** - This option writes your project to a pop-up window. You have complete control over this pop-up, so drag it around and resize it as you like. However, most inline scripts will not run [(this is intentional)](https://code.google.com/archive/p/browsersec/wikis/Part2.wiki#Same-origin_policy_for_DOM_access). This feature is really meant to help you get a feel for your project's performance, which may be on different screen sizes and resolutions.

> **In-workspace -** This option simply hides the code input boxes, and fills your workspace with the preview area. Now you can see your project in a near-fullscreen environment, scripts working and all.
