Would anyone object to including the above commands in Emacs? > The problem is what keys, if any, to bind them to by default. I'd suggest that we bind narrow-to-line to 'C-x n l', and leave mark-line unbound by default for now. > Here are some existing commands that are similar: > http://www.gnu.org/software/emacs/manual/html_node/emacs/Narrowing.html > http://www.gnu.org/software/emacs/manual/html_node/emacs/Marking-Objects.html Best regards, Stefan Kangas
