Texmaker

Texmaker is a free, cross‑platform LaTeX editor that runs on Windows, macOS and Linux. It combines a Unicode‑aware source editor with spell checking, auto‑completion, code folding and a structure view that updates while typing. The built‑in PDF viewer offers continuous scrolling, Synctex synchronization and rotation, allowing users to compile and preview documents with a single click via predefined “Quick build” commands.

The editor supports master‑file projects, enabling easy navigation across multiple source files, and includes wizards for common LaTeX constructs such as articles, Beamer presentations, letters, tables and arrays. Over 370 mathematical symbols can be inserted with one click, and users can define unlimited snippets and perform regular‑expression search and replace across folders.

Error handling is integrated: after compilation the log is parsed and warnings or errors are highlighted, with one‑click jumps to the corresponding source line. Texmaker is distributed under the GPL license and aims to provide a straightforward, configurable environment for LaTeX document creation.
