:s/pattern/\U&/g
Vim's :substitute command supports case-transformation escape sequences in the replacement string.
search #search #substitute #ex-commands #editing #text-objects
:s/pattern/replacement/e
The e flag in Vim's :substitute command silently ignores the "E486: Pattern not found" error when the pattern does not match anything.
<C-@>
Pressing (Ctrl + @, which is the NUL character) in insert mode inserts the same text that was typed during the most recent insert session, then immediately retu
:wundo {file}
The :wundo {file} command writes the current buffer's entire undo history to a file on disk.
<C-x><C-v>
The key sequence in insert mode triggers Vim command-line completion — the same completion engine used at the : command prompt.
:%center 80
Vim has three built-in Ex formatting commands — :left, :center, and :right — that align text within a specified column width.
ysiwf
vim-surround's f and F surrounds let you wrap any text object inside a function call, prompting you for the function name.
:let @a = substitute(@a, "old", "new", "g")
When a recorded macro has a typo or wrong command buried inside it, you don't have to re-record the entire thing.
:g/outer/,/end/g/inner/
The :global command accepts a range, which lets you scope its search to sections of the file rather than the entire buffer.
:put {reg}
The :put Ex command always inserts a register's content as a new line below the current line, regardless of whether the register holds characterwise, linewise,
editing #registers #editing #paste #ex-commands #normal-mode
:set regexpengine=1
Vim ships with two regex engines and lets you control which one is used.
"Ay{motion}
Using an uppercase register letter with any operator appends to the register instead of replacing it.
:s/\n/ /
One of the most confusing asymmetries in Vim's substitution syntax: \n and \r mean different things depending on whether they appear in the pattern or the repla
g- and g+
Vim's undo history is a tree, not a linear stack.
:earlier {N}m and :later {N}m
Vim's :earlier and :later commands let you travel through your edit history by wall-clock time rather than by individual undo steps.
:set cursorcolumn
:set cursorcolumn (or the short form set cuc) highlights the entire vertical column where the cursor sits, painting a visible strip from top to bottom of the wi
zO and zC
zO and zC are the recursive counterparts to zo and zc.
:e %:h/
Vim expands % to the current file's path in Ex commands, and the :h modifier strips the last filename component to give you just the directory.
:%s/\w\+/\u&/g
Vim's substitute command supports case-conversion modifiers in the replacement string.
:let @a = '...'
When a recorded macro contains a typo or needs a small tweak, you can modify it directly via the :let command rather than re-recording the entire sequence.
