  In code, all that needs to be escaped is percent, backslash and unpaired
  braces: \code{\% \\ \{}. Unescaped: \code{$ # _ ^ ~ < > |}, and as a
  pair, \code{{...}}.  If we escape: \code{ \_ \# \$ \& \{ \} \\ }
  And some backslashes: \code{\ \\ \\\ \\\\} should
  give one, one, two, two backslashes.

  How about \ (that is backslash space) in text?
  
  Elsewhere, \{ \} \% \\ need to be escaped, but not $ # _ ^ ~ < > | .
  Let's try that again in \code{\\samp}: \samp{ \{ \} \% \\ $ # _ ^ ~ < > |}.
  And if we do escape: \$ \# \_ , and with three backslashes, \\\#.

  \deqn{\$k > \#k, x_y, x\_y}
