Return to the top: <<Practical Vim>>

• show a preview of the first match based on what has been entered so far into the search field by enabled with the 'incsearch' setting

# If you open the file in vim,
# then you can \"ayy@a the next line to execute the vim command: 
:h 'incsearch'

Check for the Existence of a Match

Autocomplete the Search Field Based on Preview Match

• <C-r><C-w>
• NOTE: If you prefix your search with the \v item, then <C-r><C-w> will complete the entire word under the cursor (creating /\vcarrcarrot<CR> rather than /\vcarrot<CR> , for example) instead of the remainder of the word.
