Hi!

Brief mention of What The Hell is modal editing

• Differentiation between actually writing on the document or moving the cursor around / executing actions on the text.
• See http://www.viemu.com/a_vi_vim_graphical_cheat_sheet_tutorial.html
• Also, there are multiple plugins for multiple editors to bring vi movements to them, so even if you don't use Vim you can benefit from this!

Vim Movements

What movements can you do with regular movement keys?

• left, down, up, right (hjkl)
• line start (0), content start (for indented lines, _), line end ($)
• go to first line (gg), go to line 83 (83gg), go to last line (G)
• differentiation between word and WORD (ie foo-bar are 2 words but only 1 WORD)
  • words are sequences of letters, numbers and underscores. A dot, dash, slash or any other character marks the end of a word.
  • WORDS are sequences of non-whitespace characters.
• go to next word (w) / WORD (W)
• beginning of current/previous word (b) / WORD (B)
• end of current/next word (e) / WORD (E)
• go to matching opening/closing parentheses/bracket/square bracket (%)
• go to next paragraph (}), beginning of current/previous paragraph ({)
• also multiplied. So you can say three words forward (3w) or 8 lines up (8k).
• next character "u" in this line (fu, "find u", works with any character)
• before next character "u" in this line (tu, "til u", works with any character)
• a number before the command repeats the command that many times. (5l goes right five positions, 4rX replaces 4 characters with X)

Movements with visual mode (ie selecting text)

• Just enter "Visual" mode (v) or "Visual Line" (V) or "Visual Block" (^V) and move the cursor around with the movements we just saw.

  • If you execute a command (like delete) when you have something selected, the command acts on your selection.

• Many actions (like changing, yanking, deleting) accept a movement:

  • delete 3 words (d3w)
  • change current paragraph (c})
  • Uppercase current word (gUw)

Extra movements when selecting/issuing a command

You can act on blocks as well. Like the whole word/WORD independently on the cursor position, act on the content on parentheses or braces or html tags

• change text inside (Inside) parentheses (ci))
  • look, i here does not enter insertion mode, because the action c expects a movement.
  • similar for deleting shit inside curly braces (di}) or yanking the text inside braces (yi])
  • lowercasing text between angle brackets (gui>). Uppercasing is possible too (gUi>)
  • selecting text inside html tags (vit)
  • deleting current word (diw) or WORD (diW)
• Selecting all (All) and not just Inside
  • instead of using i as part of the movement you use a
  • ca)
  • da}
  • ...

Repeating a command: dot (.)
