1z=
The z= command opens an interactive numbered menu of spelling corrections for the word under the cursor, requiring you to type a number and press Enter.
<C-x><C-e> and <C-x><C-y>
While in insert mode, scrolls the window up one line and scrolls it down one line — all without leaving insert mode.
zR and zM
When working with a heavily folded file, manually opening or closing each fold is tedious.
<C-x><C-u>
Vim's invokes a user-defined completion function, letting you plug any completion logic you want into the standard insert-mode completion popup.
<C-x><C-i>
Vim's completion mode searches for keyword matches not just in the current buffer, but also in all files reachable via include directives (e.
:earlier 1f
The :earlier {count}f command navigates Vim's undo tree to the state of the buffer at the time of the last (or Nth) file write.
zd
zd removes the fold definition at the cursor position — the text inside the fold is not deleted.
zO
zO (uppercase O) opens the fold under the cursor and all folds nested inside it recursively.
:'<,'>center / :'<,'>right / :'<,'>left
Vim has built-in Ex commands to align text within a specified width: :center, :right, and :left.
das
Vim defines a sentence as text ending with .
editing #editing #text-objects #delete #normal-mode #motions
:[range]join
The :[range]join Ex command lets you join lines by specifying an explicit line range — without having to navigate there or use visual selection.
:%s/\r//g
When a file created on Windows is opened in Vim on a Unix system, lines may retain \r (carriage return) characters, displayed as ^M at the end of each line.
:[range]center [width]
Vim's built-in :left, :center, and :right Ex commands align text without plugins or external tools.
inoremap <Left> <C-g>U<Left>
In insert mode, any cursor movement — including arrow keys, Home, and End — causes Vim to split the undo block at that point.
:s/\v\w+/\U&/g
Vim's substitute command supports special case-conversion sequences in the replacement string, letting you transform matched text to upper or lower case without
!{motion}{cmd}<CR>
In normal mode, !{motion} sends the lines covered by the motion to a shell command's stdin and replaces them with stdout.
:sort n
:sort n sorts lines by the first number found on each line, comparing values numerically rather than as strings.
<C-o> (insert mode)
Pressing while in insert mode lets you execute exactly one normal mode command and then automatically returns you to insert mode.
:center, :right, :left
Vim includes three built-in Ex commands for text alignment that most users never discover: :center, :right, and :left.
<C-x><C-]>
Pressing in insert mode opens a completion menu populated from your project's tags file.
