Jed is a powerful text editor written by John E. Davis.
I always use Jed with the Borland-like IDE mode, and I use it mainly for writing LaTeX documents.
The purpose of this LaTeX is to provide useful tools for writing and
editing LaTeX files, to manage projects with several LaTeX input files,
to define simple interfaces to the latex/pdflatex engine and the
previewer, printer, bibtex, etc., and to make it easy to jump from an
error message to the corresponding line in the input file.
The editing tools include simple insertion/marking/renaming of
environments (with special support for a few often used environments),
a configurable indentation routine, and a `find matching LaTeX
delimiter' tool.
The mode employs the ususal idea of a main file (or primary file or
master file). All operations such as composing, previewing, printing,
bibtex'ing etc. are done on the main file.
When the compose process has terminated, the error messages (if any) are
rewritten in a format that can be handled by Jed's standard error
parsing functions; the user can then step through the list of errors
while the cursor keeps pointing to the corresponding input line.
