Hi Omar,

I recognised the use of the form feed ^L (ASCII 12) from Emacs. I was wondering about that too.

I checked the perspective from Xah Lee, who has evaluated its applicability:=

http://ergoemacs.org/emacs/modernization_formfeed.html

He highlights technical limitations of form feed's reliance on ^L:```# Cygwin BashCygwin Bash will generate this error if your shell script contains the Form Feed char that's not in comment.

bash: \f': command not found

AutoHotkeyAutoHotkey scripting language generates compiler error if you have a uncommented Form Feed char in source code.

PHPPHP would print a warning about it: “Warning: Unexpected character in the input: '^L' (ASCII=12)”. This is in PHP bug database```

His suggestion is an abbrev is to modernise the technique and encourage interprability

So, a workaround i came up is to use the Unicode SECTION SIGN §, followed by the Unicode BOX DRAWINGS LIGHT HORIZONTAL (U+2500) ─.``` elisp("ss" "§ ────────── ────────── ────────── ────────── ──────────")

Incidentally, should a browser ever consider navigating sections Xah Lee cites the use of `[` and `]` characters but proposes `PageUp` and  `PageDown`.
