... standard "folding" mode.

I have an uncomplete implementation of a folding mode based on regular
expressions (pcre) that build upon the filter-buffer mode on Jedmodes,
http://jedmodes.sourceforge.net/mode/filter-buffer/

I would like to see it as a display alternative to the HORIZONTAL_PAN
of overlong lines.

Given its small footprint, Jed is an ideal editor for netbooks or the XO
laptop. I did, however, experience problems with the "archaic" font setup
for xjed. Even after heavy experimenting with font settings in my
~/.Xresources the resulting font is either too large for the small screen
or too pixly and too small for easy reading.  In contrast, many
X-terminal-emulators enable easy font selection and usage of a wide range
of fonts via the fontconfig library.

Thus I end up with the choice of either limited keybindings or limited
readabilty.
