Highlight sentences in Emacs with a custom face. Very nice.
Customizing the Face
Highlighting is based on the
hl-sentence face which you can
customize to make the face look the way you want. I use this
primarily in LaTeX mode where I enable
variable-pitch-mode. So I
variable-pitch face foreground to be
gray60 and then
black. Works nicely.
This was taken mostly from http://www.emacswiki.org/emacs/SentenceHighlight
I believe Aaron Hawley is responsible. I just took it and made it a single file and to properly enable and disable the minor-mode.
