is it possible to spell check PDF files? Is it possible to spell check PDF files? In Preview.app the "Edit > Spelling &amp; Grammar > Check Document Now (⌘;)" is disabled. I'm working on a LaTeX document in Emacs and would like to use the OS X spell checker. A solution for accessing the built in spellchecking dictionary from Emacs would also be acceptable.
I would install aspell with a package manager like brew and then run that on the .tex file. Unless I'm mistaken emacs has support for aspell built-in.

You can also turn on spell checking in your terminal (iterm2) or emacs GUI.
