CCA EMACS has been modified so that any one of three separate indenting styles can be chosen for Lisp mode, depending on the setting of the variable Lisp Indent. A Tab at the beginning of a line will always indent using a narrow style of indentation if the variable Lisp Indent is -1; it will indent with a wide style for the first level and with a narrow style thereafter if Lisp Indent is zero (the default); and it will always indent with a wide style of indentation if Lisp Indent is 1. Furthermore, a Tab given anywhere else in the line will now line up with the next field in the previous line. It is now possible to send arbitrary regions of text as mail. The old ^R Mail Buffer command has been replaced with a completely new command ^R Mail Region, which, like the old command, may be invoked with C-X M. You will be prompted for the To, Cc, and Subject fields; the Cc and Subject fields may be left blank if desired. A tilde in the first column of any line in your region will activate the appropriate tilde escape in mail; this allows you to do things such as include Bcc fields in your messages. Any error messages produced by the mail program will be displayed.
