How do I append keystrokes to a macro without re-recording it?
:let @q .= 'j'
Re-recording a long macro just to add one extra keystroke is wasteful and error-prone.

How do I refactor a recorded macro by rewriting its keystrokes with substitute()?
:let @q = substitute(@q, 'foo', 'bar', 'g')
Recorded macros are plain text stored in registers, which means you can refactor them instead of re-recording from scratch.
How do I append new keystrokes to an existing macro register without re-recording it?
:let @q .= 'A;<Esc>'
Re-recording a long macro just to add one extra step is slow and error-prone.
How do I insert a timestamp computed by Vimscript directly from Normal mode?
"=strftime('%Y-%m-%d %H:%M')<CR>p
The expression register lets you evaluate Vimscript on demand and paste the result immediately.

How do I run a one-off macro without recording by executing keystrokes from an expression register?
@='A;<Esc>'<CR>
Recorded macros are powerful, but sometimes you need a quick ephemeral sequence and do not want to occupy a register.
How do I trim trailing whitespace while preserving marks, jumplist, and search state?
:lockmarks keepjumps keeppatterns %s/\s\+$//e
Bulk cleanup commands are easy to automate, but many implementations quietly damage editor state by moving marks, polluting the jumplist, or replacing your last
How do I execute a macro on each quickfix match and write files only when changed?
:cdo normal! @a | update
When you already have a precise quickfix list, :cdo is one of the safest ways to run a macro only where it matters.
How do I apply my last normal-mode change to every line in a visual selection?
:'<,'>normal! .
When you already made one correct edit, replaying it is usually safer than retyping it by hand.
How do I edit an existing macro by modifying its register text instead of rerecording it?
:let @q = substitute(@q, '\n$', 'A;<Esc>\n', '')
Rerecording a long macro for one tiny change is slow and error-prone.
How do I evaluate a Vim expression and paste the result directly from a register?
"=strftime('%F')<CR>p
The expression register lets you compute text on demand and insert it without leaving Normal mode workflows.

How do I replay macro q from command-line mode without changing @/?
:keeppatterns normal! @q<CR>
When you replay macros from Ex commands, Vim can overwrite @/ (the last search pattern) depending on what the macro does.
How do I get exact current and total counts for my last search pattern in Vim?
:echo searchcount({'recompute': 1})
Vim can show match counts for your last search, but in large files or after big edits the cached values may lag.
search #search #command-line #automation #statusline #diagnostics
How do I repeatedly run a macro while a pattern is still found in the buffer?
:while search('TODO') | normal! @q | endwhile
A fixed count like 100@q is brittle: sometimes your macro needs 12 passes, sometimes 300, and over-running can corrupt already-processed text.

How do I append the current filename to a named register from Ex command-line?
:let @a .= expand('%:t') . "\n"
Named registers are not just for yanks and deletes.
How do I execute a recorded macro once in each currently open window?
:windo normal! @q
When you split a file into multiple windows or keep several related buffers visible, repeating the same small cleanup in each one can be tedious.

How do I inspect a register as a list of lines in Vimscript?
:echo getreg('a', 1, 1)
For advanced register debugging and macro tooling, plain getreg('a') is often not enough.
How do I append keystrokes to an existing macro without re-recording it?
:let @q .= "A;\<Esc>"
If a recorded macro is almost correct but missing a final step, re-recording from scratch is slow and error-prone.
How do I run a Normal-mode command through :execute in Vim?
:execute "normal! gg=G"<CR>
:execute lets you build and run Ex commands dynamically, which is critical when a command depends on variables, conditionals, or string composition.
command-line #command-line #ex-commands #normal-mode #automation
How do I execute Ex commands stored in a register instead of replaying it as normal-mode keys?
:@q
Most macro workflows focus on @q, which replays register q as normal-mode keystrokes.
How do I append the same suffix to every selected line in Visual mode?
:'<,'>normal! A;
Visual selections are not just for direct operators; they also define an Ex range.
