Visual Mode Tips​

Efficiency Tips​

  1. Use text objects - viw, vip, vi" for quick selections
  2. Use block mode for column operations
  3. Use gv to reselect last selection
  4. Use o to move to other end of selection
  5. Combine with operators for powerful editing

Common Patterns​

vip     " Select paragraph
vi{     " Select inside braces
va"     " Select around quotes
V/end   " Select lines until pattern

Block Mode Patterns​

Ctrl+v G I    " Insert at beginning of all lines
Ctrl+v $ A    " Insert at end of all lines
Ctrl+v 5j c   " Change 5-line column

Visual Mode Best Practices​

When to Use Each Mode​

  • Character mode (v): For selecting partial lines, words, or phrases
  • Line mode (V): For selecting complete lines or paragraphs
  • Block mode (Ctrl+v): For column editing, tables, or aligned text

Avoiding Common Mistakes​

  1. Don't forget to exit visual mode with <Esc> when done
  2. Use appropriate mode for your selection needs
  3. Remember that operations work on entire selection
  4. Use gv to reselect instead of manually reselecting

Combining with Other Features​

v/pattern<CR>d    " Select to pattern and delete
V}:sort<CR>       " Select to paragraph end and sort
Ctrl+v G $y       " Select entire columns and yank

Visual Mode and Macros​

Recording Macros with Visual Mode​

qa           " Start recording macro 'a'
v3w          " Select 3 words
>            " Indent selection
q            " Stop recording
@a           " Play macro

Visual Mode in Macro Playback​

V            " Select line
@a           " Apply macro to selection

Troubleshooting Visual Mode​

Common Issues​

  1. Selection not what expected - Check which visual mode you're in
  2. Can't exit visual mode - Press <Esc> or Ctrl+c
  3. Operations not working - Ensure you're in the right visual mode
  4. Block mode not aligning - Check tab settings and alignment

Debug Tips​

:set number       " Show line numbers for reference
:set list         " Show whitespace characters
:set ruler        " Show cursor position
