There are (in my mind) two types of word wrapping:
- Hard : Actually edit the file to have lines of a maximum length
- Soft : Just wrap in the editor, but the underlying file still has long lines.
I can't figure out how to make Emacs do these two different types of word wrapping (most people just talk about "word wrap", without distinguishing which they are talking about).
C-h rto visit the Emacs manual. Theni wrap TAB RET. That completeswraptowrappingand then visits the part of the manual (node Continuation Lines) that talks about this. In that node you also find a link to node Visual Line Mode, which talks about your "soft" wrapping. – Drew Sep 23 '16 at 16:20
