# Entry editor tabs

{% hint style="info" %}
Since the entry editor's redesign, it is no longer possible to define custom tabs with an arbitrary set of fields. All fields of an entry are shown together in the entry editor's [Main tab](/advanced/entryeditor.md#the-main-tab), grouped into collapsible sections (Identifiers, Files and links, Bibliometrics, Comments, Meta). The rest of this page describes the tabs that remain configurable.
{% endhint %}

You can choose which of the entry editor's built-in tabs are shown, and in which order, under **File → Preferences → Entry Editor → Editor tabs**. Untick a tab to hide it for all entry types; the tab list includes the Main tab, Bib(la)TeX source, Related articles, AI summary, AI chat, File annotations, LaTeX citations, Citations and Fulltext search results.

It does not matter how a field's name is capitalised. In the entry editor, normally a field's first letter is capitalised, i.e. *abstract* is represented as *Abstract*, *KEYwords* would be represented as *Keywords* (*DOI*, *ISBN*, *URL* are exceptions in that all letters are capitalised). In the bibtex code, all field names use lower case: *KEYwords* is *keywords* in the entry's bibtex code.
