:iabbrev {lhs} {rhs}
The :iabbrev command defines insert-mode abbreviations — short character sequences that automatically expand into longer text when you type a non-keyword char
zv
zv (view cursor) opens the minimum number of folds needed to make the current line visible — nothing more.
: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
: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
<C-u> in insert mode
Pressing while in insert mode deletes all characters entered since you last entered insert mode on the current line.
gw
The gw operator reformats text to fit within textwidth, just like gq — but with one key difference: gw leaves the cursor in its original position after format
:'<,'>norm! A;
The :normal Ex command lets you execute any Normal mode keystrokes on a range of lines simultaneously, turning a single-line operation into a multi-line batch e

<C-f>
While typing in Vim's command line (after pressing :), pressing opens the command-line window with your current, unfinished command already filled in.
:set formatprg={program}
Vim's gq operator normally reflows text to fit textwidth, but by setting formatprg you can delegate formatting to any external tool — a language formatter, a
:~
The :~ command repeats the last substitution but uses the current search pattern instead of the original pattern.
ZQ
ZQ is the discard-and-quit counterpart to ZZ.
8g8
The 8g8 command searches forward from the cursor for the first byte that belongs to an invalid UTF-8 sequence.
% (in netrw)
Vim's built-in file explorer netrw (opened with :Explore or :Ex) is more capable than it looks.
{count}J
The J command joins the current line with the line below, adding a space between them.
:set nrformats+=bin
Vim's and commands increment and decrement numbers under the cursor, but by default they only handle decimal and hexadecimal.
:set number relativenumber
Enabling both number and relativenumber simultaneously activates hybrid line numbering: the current line displays its true absolute line number while every othe
:set winfixwidth
Setting winfixwidth on a window tells Vim not to adjust its width when other windows are created, closed, or resized with =.
<C-f> (in command line)
Pressing while you are already typing in the Vim command line (:), search line (/ or ?), or input prompt switches you into the command-line window with the curr

zfap
Combining the fold-creation operator zf with the ap (around paragraph) text object gives you a quick way to collapse any paragraph into a single fold line.
