[<C-d>
Vim's [ command jumps to the first definition of the macro or identifier under the cursor, searching from the beginning of the current file and through any file
q?
Vim provides three command-line history windows accessible from normal mode: q: for Ex commands, q/ for forward searches, and q? for backward searches.
<C-r><C-r>
In command-line mode, {reg} inserts a register's contents — but it processes certain sequences, potentially misinterpreting backslashes, pipe characters, or e
<C-v> (command-line mode)
In command-line mode (after : or /), pressing followed by any key inserts that key literally — bypassing all key notation, mappings, and special interpretatio
:%s/\n/ /g
Using \n in the pattern of :substitute matches the newline character at the end of each line, letting you join lines with any separator you choose — something
\%(...\)
Vim's standard grouping syntax \(.
:g/^\s*$/d
The global command :g/^\s$/d removes every line that is empty or contains only whitespace — a common cleanup task when tidying up code, configuration files, o
\n in search, \r in replacement
Vim uses \n and \r differently depending on whether they appear in a search pattern or a replacement string, and mixing them up is a common source of confusion.
zG
zG marks the word under the cursor as correctly spelled in Vim's internal word list, which exists only for the current session.
searchcount()
The searchcount() function returns a dictionary containing the current search state: which match the cursor is on, how many total matches exist, and whether the
:Telescope resume
The :Telescope resume command reopens the most recent Telescope picker, restoring the exact query string, filtered results, and cursor position from the last ti
:2match Todo /FIXME/
Vim provides three independent match slots — :match, :2match, and :3match — each of which highlights a pattern using a specified highlight group.
/pattern\c
Vim's \c and \C atoms let you override the global ignorecase and smartcase settings on a per-search basis.
:g/pattern/+1d
Using :g/pattern/+1d you can delete the line that comes right after each line matching a pattern, in one pass.
:%s/\v(\w+)/\u\1/g
Vim's substitute command supports case-modifier escapes in the replacement string: \u uppercases the next character, \U uppercases all text until \E or end of r
/pattern\C
Appending \C anywhere in a search pattern forces the entire search to be case-sensitive, regardless of whether ignorecase or smartcase is set.
search #search #case-sensitive #ignorecase #smartcase #normal-mode
:set grepprg={cmd} grepformat={fmt}
Vim's :grep command delegates to an external tool defined by grepprg, then parses the output according to grepformat to populate the quickfix list.
:spellrepall
After correcting a misspelled word with z= (or 1z= for the first suggestion), run :spellrepall to apply that same correction to every other occurrence of the id
\@= and \@<=
Vim's regex engine supports zero-width lookahead and lookbehind assertions — \@= and \@<= — which let you match text based on surrounding context without in
matchlist()
matchlist({str}, {pattern}) runs a regex match and returns a list of all captured groups, making it the idiomatic way to extract structured data from strings in
