For commenting a artifact of matter is about the aforesaid:

  1. Archetypal, spell to the archetypal formation you privation to remark, estate CtrlV. This volition option the application successful the Ocular Artifact manner.
  2. Past utilizing the arrow cardinal and choice till the past formation
  3. Present estate DisplacementI, which volition option the application successful INSERT manner and past estate #. This volition adhd a hash to the archetypal formation.
  4. Past estate Esc (springiness it a 2nd), and it volition insert a # quality connected each another chosen strains.

For the stripped-behind interpretation of vim shipped with debian/ubuntu by default, kind : s/^/# successful the 3rd measure alternatively (immoderate remaining highlighting of the archetypal quality of all formation tin beryllium eliminated with :nohl).
