BTW, I recently wrote a program for a similar purpose. I called it
tless (less with terminal control sequences sequences). It allows to
step forward and back through a file with escape sequences. Stepping
back is done be re-writing the complete file up to the new position,
so it's not well suited for larger files. It's quite primitive, but
it has worked for me. If anyone is interested, I've put it at
