Enter TeX is a TeX/LaTeX text editor. The application was previously named LaTeXila and then GNOME LaTeX. Its development started in 2009.
Enter TeX permits to focus on the content and the structure of the document.
To help the writing of the LaTeX markup, auto-completion is available as well as menus and toolbars with the principal commands. New documents are created from templates. There are buttons to compile, convert and view a document in one click. And projects containing several .tex files are managed easily.
A side panel contains three components: the document structure to easily navigate in it; lists of symbols to insert them in a document; and a file browser.
Enter TeX has also other features like the spell-checking, or jumping to the associated position between the .tex file and the PDF.
