does not have an integrated text editor, but if you are using
System 7 or later you won't find this too much of a problem.
After installing and starting it up for the very first time,
select ``Choose Editor'' from the Edit menu and use the
open-file dialog to locate and select the application you'll be using
to edit your TEX/LATEX input files.
If the chosen application supports Apple events then remembers
its name and location for use in all future sessions (or until
you choose another editor).
Having chosen an editor, will use it as the target of an
``open file'' event sent when you select ``Edit foo.tex'' from the Edit menu.
This item always shows the name of the most recently typeset file.
See section
for more details about the items in the Edit menu.
