2021.12.15 - GNU nano 6.0  "Humor heeft ook zijn leuke kanten"

=E2=80=A2 Option --zero hides the title bar, status bar and help lines, a=
nd
  uses all rows of the terminal as editing area.  The title bar and
  status bar can be toggled with M-Z.
=E2=80=A2 Colors can now be specified also as three-digit hexadecimal num=
bers,
  in the format #rgb.  This picks from the 216 index colors (that most
  terminals know) the color that is nearest to the given values.
=E2=80=A2 For users who dislike numbers, there are fourteen new color nam=
es:
  rosy, beet, plum, sea, sky, slate, teal, sage, brown, ocher, sand,
  tawny, brick, and crimson.
=E2=80=A2 Suspension is enabled by default, invokable with ^T^Z.  The opt=
ions
  -z, --suspendable, and 'set suspendable' are obsolete and ignored.
  (In case you want to be able to suspend nano with a single keystroke,
  you can put 'bind ^Z suspend main' in your nanorc.)
=E2=80=A2 When automatic hard-wrapping is in effect, pasting just a few w=
ords
  (without a line break) will now hard-wrap the line when needed.
=E2=80=A2 Toggling Append or Prepend clears the current filename.
=E2=80=A2 The word count as shown by M-D is now affected by option --word=
bounds;
  with it, nano counts words as 'wc' does; without it (the new default),
  words are counted in a more human way: seeing punctuation as space.
=E2=80=A2 The YAML syntax file is now actually included in the tarball.


GNU nano is a simple and easy-to-use editor for on the terminal.
