RE: Why do I find ^L in elisp code?

[arthur miller <arthur.miller@live.com>]

Yeah, both wasamasa and Purcell have some code to render page breaks prettier:

https://github.com/purcell/page-break-lines

https://depp.brause.cc/form-feed/

And if I remember well there was some interesting article by Mr. Kitchin which I can't find at the moment.

Otherwise, there is some read on wiki pages about page breaks:

I'm not an emacs dev, but I find the form feed handy.  Emacs (what other
editors do shouldn't be too much important, should we drop elisp too
since no other editors has a lisp core? :P) has some really handy
functions to handle pages, I encourage you to try to use them sometimes.

It's not really hard to type, just a C-q C-l, and, at least here on
emacs on x11, it's rendered as '^L'.  I've seen tricks to render it as
an horizontal rule.
