[NTG-context] Formatting lines in TeXworks and using spellchecking

Until now I worked with Emacs to edit ConTeXt documents. Because I have to make a manual for the client, I now work under Windows with TeXworks. In Emacs I could easily reformat my (source) lines, to be not wider as 72 characters. Is something like that possible with TeXworks. Also: there is a spell-checking option, bet there are no languages to choose from. How can I install languages? -- Cecil Westerhof
