viw
How it works The command viw selects the word under the cursor in visual mode.
gM
The gM command moves the cursor to the horizontal middle of the current line, regardless of how long the line is.
:set foldmethod=expr
Setting foldmethod=expr tells Vim to call the foldexpr expression for every line to compute its fold level.
:e ++enc=utf-8
When Vim opens a file with the wrong encoding — producing garbled text or incorrect characters — you can reload it with a specific encoding using :e ++enc={
:diffthis
You often have two files open side by side and want to compare them without leaving Vim or launching vimdiff.
:let @q = "dwelp"
Recording macros with q works well for simple sequences, but complex macros with special keys can be hard to get right in one take.
:vimgrep /pattern/ %
When you need to find all occurrences of a pattern in the current file and jump between them systematically, :vimgrep with % is more powerful than basic / searc
:let view=winsaveview() | {cmd} | call winrestview(view)
When writing Vimscript functions or mappings, commands like :substitute, gg, or :%normal will move the cursor and change the scroll position.
:set nomodifiable
:set nomodifiable locks a buffer so that no changes can be made at all — not even temporary ones.
:noautocmd e {file}
When you have heavy autocmds registered for BufRead, BufEnter, or FileType events — such as LSP clients, formatters, or syntax processors — opening a large

:set isfname+=@-@
gf is fast until it stops exactly at characters common in modern import paths, especially @ in scoped package names (@org/pkg/file).
:sbuffer {N}
:sbuffer {N} opens buffer number N in a new horizontal split, leaving your current window untouched.

/pattern1\&pattern2
Vim's \& operator lets you intersect two patterns so the match must satisfy both simultaneously.
:let @a = @a . "\<CR>extra"
Vim stores macros as plain text in registers — the same registers used for yanked text.
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
\%#
The \%# atom in Vim's regex engine matches the exact position of the cursor — zero-width, between characters.
:cnoremap %% <C-r>=expand('%:h').'/'<CR>
By mapping %% in command-line mode, you can type %% wherever you would normally type a path and have Vim automatically expand it to the directory of the current
vim.filetype.add()
vim.
:argdo norm @a | update
Combining :argdo with :norm @a lets you apply a recorded macro to every file in Vim's argument list — a powerful pattern for bulk refactoring across a project
