:'>,'<normal @q
Running a macro over a range usually goes top to bottom, but that can break when the macro inserts or deletes lines.

:g/^/m0
The :g/^/m0 command is a clever use of Vim's global command to reverse every line in the file.
\d \w \s \a \l \u
How it works Vim provides shorthand character classes that save you from writing out full bracket expressions.
:2match Todo /FIXME/
Vim provides three independent match slots — :match, :2match, and :3match — each of which highlights a pattern using a specified highlight group.
systemlist()
systemlist({cmd}) runs a shell command and returns the output as a list of strings, one per line — unlike system() which returns everything as a single string
:let @q = substitute(@q, '\n', '', 'g')
A common macro failure mode is accidentally hitting while recording.
:%s/#\zs\d\+/\=printf('%04d', submatch(0))/g
For log files, changelogs, or issue references, you sometimes need fixed-width numeric IDs without touching surrounding syntax.

:'<,'>s/\%V\s\+$//
Sometimes you need to clean alignment artifacts in a rectangular region without touching the rest of each line.

:tab help
By default, :help opens in a horizontal split, which can feel cramped.
:cdo keepjumps keeppatterns %s/\<OldSymbol\>/NewSymbol/ge | update
When you run :cdo over a large quickfix list, Vim can leave your jump list noisy and your last search pattern overwritten.

:set shortmess+=I
The shortmess option is a string of single-character flags that tell Vim which messages to suppress or abbreviate.
:%s/\vfoo\zsbar/baz/g
When your match has a stable prefix but you only want to replace the trailing segment, \zs is often cleaner than introducing extra capture groups.
:s/\v(\w+)\s+(\w+)/\2 \1/
By using capture groups in a substitute command with very magic mode (\v), you can swap two adjacent words in a single operation.
:redir @a | messages | redir END<CR>
When debugging a session or building repeatable edits, it is useful to turn command output into editable text.
:cexpr system('rg --vimgrep "TODO"')
When you already know you want an external search tool, :cexpr lets you import results directly into quickfix without opening a terminal buffer or shelling out
:vimgrep /\<TODO\>/gj **/*.lua | copen
When you want a project-wide TODO pass without leaving Vim, :vimgrep plus quickfix is a strong built-in workflow.

:bufdo if &buftype ==# '' | update | endif
bufdo is powerful for multi-buffer automation, but a naive write pass can error on special buffers (help, terminal, quickfix, prompts).

:g/BEGIN/+1,/END/-1 delete
By combining the :global command with a relative address range, you can delete the content between repeating delimiter pairs while leaving the delimiters intact
{count}n
Like most Vim motions, the n and N search repeat commands accept a count prefix.
:argdo if search('\s\+$', 'nw') | echo expand('%') | endif
Before running destructive cleanup across many files, it helps to know which files will actually change.
