# Entry preview setup

## Location

The **Entry Preview** is located inside the **Entry Editor** (except when navigated to the `File annotations` or `{} biblatex source` tab):

![Entry Preview](https://2944476579-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-Lr3JU9j9iSUW8RYz1hD-2910905616%2Fuploads%2Fgit-blob-1617c3d4bb3cab1a00e96a5672099e6bddd040ae%2Fentryeditor-preview.png?alt=media\&token=399935d5-8a96-4d37-8431-8760704a4324)

You can display the entry preview as a separate tab (see screenshot above) by checking the box `Show preview as a tab in entry editor` in the entry preview settings `Options > Preferences > Entry preview > Current Preview` (see screenshot below).

## Layouts/Styles

The entry preview displays either the **Customized Preview Style** or a certain **Citation Style**. You can select the styles that should be available for display in **Options → Preferences → Entry preview**. In `Available` you find all styles selectable for display, in `Selected` all styles already selected for display:

You can switch between all selected styles (customized preview and citation styles) in the entry preview in the main window by pressing `F9`.

## Display Mechanism

The layout is automatically created using the same mechanism as used by the [Custom export filter](https://docs.jabref.org/collaborative-work/export/customexports) facility. When previewed, an entry is processed using one of the selected layouts/styles to produce HTML code which is displayed by the preview panel.

## Modification of the Customized Preview Style

To customize the appearance and contents of the customize entry preview you need to edit/modify the customized preview style in the entry preview settings (see screenshot above) using the custom export filter syntax described in the [Documentation](https://docs.jabref.org/collaborative-work/export/customexports).
