A. Is there a spellchecker built in to Emacs?
This seems to say that there is a "built-in ispell package" that "handles spell-checking and correction".
The manual (Emacs > Fixit > Spelling > 16.4) makes it sound like nothing is built in: "These commands only work if the spelling checker program Aspell, Ispell or Hunspell is installed. These programs are not part of Emacs, but one of them is usually installed in GNU/Linux and other free operating systems."
B. If there is a spellchecker built in to Emacs, how do I use it? The commands in the manual (Emacs > Fixit > Spelling > 16.4) do not work.
When I try "M-x ispell", I get this:
Starting new Ispell process ispell with default dictionary... apply: Searching for program: no such file or directory, ispell
C. If there is not a spellchecker built in to Emacs, what is the most simple way to get one working on a Windows 8 or 10 machine? I don't even care about "on-the-fly" spellchecking. I'd be happy with being able to type a command and have the spellchecker check the buffer.
