Neither does \\\\= or \\\= To print the sequence "\\=" as a string but not as a doc string escape sequence, using "\\\\=" does work. But if you want to print it in the context of a doc string escape sequence, you have to double it, just like you have to double "\" in normal Lisp strings.

It works in the example I gave just above. As so often you have not provided a complete reproducer, so I can only try to guess why what you did does not work. But I won't guess now.

Thank you, now I can reproduce the problem. From brief testing it seems "\\\\=" in a doc string only prints as "\\=" when it is the final character sequence in the doc string. This could be a bug but I don't have time to debug it now. However, escaping "\\=" as above does work: (defvar mydocstring "" "In the docstring, apply the escape sequence \\\\=\\=\\= to stop conversion by `substitute-command-keys'.") So I guess the recommendation is to always use this if you want to see "\\=" in a *Help* buffer. Steve Berman ^ permalink raw reply [flat|nested] 7+ messages in thread

After seeing your post about the discussion of substitute-command-keys in the Elisp manual, and re-reading that section, I have to make what I wrote above more precise: to make "\\=" appear in a *Help* buffer by itself, i.e. not functioning as an escape sequence, write "\\\\=\\=" in the doc string; to make "\\=" appear in a *Help* buffer in a context where it functions as an escape sequence, write "\\\\=\\=\\=" in the doc string. So in the above example of a doc string for the variable `mydocstring', "\\\\=\\=" suffices. Steve Berman ^ permalink raw reply [flat|nested] 7+ messages in thread
