The entry editor opens from main window (table of entries). To open it for a specific entry, you can either:
double-click on the entry in the table of entries
select the entry and press Enter
select the entry and go to the menu View → Open entry editor
select the entry and press CTRL + E
Then you can modify the content of the entry (see below). When done, click on the top left-hand corner of the entry editor or press ESC to close the entry editor and go back to the table of entries.
In this panel you can specify all relevant information on a single entry. The entry editor checks the type of your entry, and lists all the fields that are required, and the ones that are optional, for referring the entry with BibTeX. In addition, there are several fields termed General fields, that are common to all entry types.
You can fully customize which fields should be regarded as required and optional for each type of entry, and which fields appear in the General fields tabs. See Customizing entry types for more information about this.
For information about how the fields should be filled out, see BibTeX help.
The entry editor's panels
The entry editor contains six panels: Required fields, Optional fields, General, Abstract, Comments and Bib(la)TeX source, where General, Abstract and Comments can be customized (see Customizing general fields for details). Inside the three first panels, Tab and Shift + Tab are used to switch focus between the text fields.
Up to JabRef 4.1, the field was called "Review". The field name was changed to "Comments" as "Review" indicated some external reviews or some fundamental comments.
Switch panels by clicking on the tabs, or navigate to the panel to the left or right using the following key combinations: Ctrl + Tab or Ctrl + + switch to the tab to the right, and Ctrl + Shift + Tab or Ctrl + - switch to the tab to the left. You can also switch to the next or previous entry by pressing Ctrl + Shift + Down or Ctrl + Shift + Up, respectively, or by clicking the appropriate toolbar button.
BibTeX source (termed biblatexsource in case of a biblatex library) shows how th entry will appear when the database is saved in BibTeX (or biblatex) format. If you wish, you can edit the source directly in this panel. When you move to a different panel, press Ctrl + S or close the entry editor, JabRef will try to parse the contents of the source panel. If there are problems, you will be notified, and given the option to edit your entry further, or to revert to the former contents.
Tip: If your database contains fields unknown to JabRef, these will be visible in the source panel.
Tip: the pdf and url fields support Drag and Drop operations. You can drop there an url from your browser. either a link to a pdf file (that JabRef can download for you) or you can keep the link.
Field consistency checking
When the contents of a field is changed, JabRef checks if the new contents are acceptable. For field types that are used by BibTeX, the contents are checked with respect to the use of the '#' character. The hash symbol is only to be used in pairs (except in escaped form, '\#'), wrapping the name of a BibTeX string that is referenced. Note that JabRef does not check if the referenced string actually exists (this is not trivial, since the BibTeX style you use can define an arbitrary set of strings unknown to JabRef).
If the contents are not accepted, the field will turn red, indicating an error. In this case the change will not be stored.
Handling of string constants
BibTeX supports string constants. One can define in the bibliography. JabRef offers editing of these strings via the String Editor.
For instance, if you see #jan# in the month field, the "real" BibTeX entry looks like month = jan. For more details, see Strings.
The entry editor offers autocompletion of words. In the Options → Preferences → Entry editor, you can enable or disable autocompletion, and choose for which fields autocompletion is active.
With autocompletion, JabRef records all words that appear in each of the chosen fields throughout your database. Whenever you write the beginning of one of these words, it will be suggested visually. To ignore the suggestion, simply write on. To accept the suggestion, either press Enter or use your arrow keys or other keys to remove the selection box around the suggested characters.
Note: the words considered for suggestion are only the ones appearing in the same field in entries of the same database as the one you are editing. There are many ways to realise this kind of feature, and if you feel it should have been implemented differently, we'd like to hear your suggestions!
Drag and drop behavior settings
The entry editor allows for file(s) to be dragged and dropped directly into the entry editor window. JabRef follows the default behavior of your operating system and uses Modifier keys to distinguish the drag and drop options. Copy means the entry editor will create a copy of the file in the current directory. The keyboard shortcuts needed to move, copy or link files are the following: Move means, the entry will move the file to the defined file directory, and rename the file according to the filename and file directory patterns. Link means the entry editor will create a link to the file. This creates a shortcut to the file and will not copy the file to the current directory.
Move: Ctrl + Drag (Windows) or Option + Drag (MacOS/Linux)
Copy: Shift + Drag (Windows) or Command + Drag (MacOS/Linux) or no key + Drag
Link: Alt + Drag (Windows) or Command + Option + Drag (MacOS/Linux)
Copy citation key including citation command
Pressing Ctrl + K or the 'key' button causes the citation key for your entry including the surrounding to be copied to the clipboard.
Copy citation key
Pressing Ctrl + Shift + K causes the citation key for your entry to be copied to the clipboard.
Autogenerate citation key
Press Ctrl + G or the 'gen key' button (the magic wand) to autogenerate a citation key for your entry based on the contents of its required fields.
