:diffupdate
After making edits in a vimdiff session, the diff highlighting can become out of sync with the actual content — showing incorrect change markers or missing hu
:view {file}
:view opens a file with the readonly option set, preventing accidental writes.
:tabmove +1
:tabmove normally takes an absolute position (:tabmove 0 moves the tab to the far left), but it also accepts relative offsets using + and -.
:set cursorbind
:set cursorbind (or :setlocal cursorbind) locks the cursor's column position so it moves in sync across all windows that have cursorbind enabled.
:diffget LOCAL
When Vim is configured as a git mergetool, it opens a three-way split with the LOCAL (your branch), REMOTE (their branch), and MERGED (the output file) buffers.

:tabdo
The :tabdo {cmd} command executes an Ex command in each open tab page sequentially, visiting every tab and running the command there.

:set splitkeep=screen
Controls how Neovim preserves the visual position of content when creating, closing, or resizing horizontal splits.
:split #
In Vim, # is a special filename that always refers to the alternate file — the most recently active buffer before the current one.
:mksession
:mksession saves a snapshot of the current Vim session — all open buffers, window splits, tab pages, cursor positions, and folds — to a file called Session.
<C-w>g<C-]>
Pressing g jumps to the definition of the tag under the cursor — just like — but opens the destination in a new horizontal split window.
:w !diff % -
The command :w !diff % - pipes the current buffer's contents to an external diff command that compares it against the saved file on disk.

:sp +/{pattern} {file}
The +{cmd} syntax lets you run an Ex command immediately after a file is opened.
:tab {cmd}
Most commands that open a new window (:help, :split, :new, :terminal) open a horizontal split by default.
:bufdo {cmd}
:bufdo executes an Ex command in each open buffer in sequence, cycling through every buffer in the buffer list.
:sball
The :sball command (short for split all) opens every loaded buffer in its own horizontal split window in one shot.
:set switchbuf=useopen
The switchbuf option controls how Vim decides where to display a buffer when switching to it via commands like :sb, :cc, :cn, quickfix jumps, or .

:set sessionoptions
The sessionoptions option (abbreviated ssop) is a comma-separated list of flags that determine what :mksession stores in the session file.

:args **/*.js
The :args command populates Vim's argument list with files matching a glob pattern, turning any set of files into a navigable list and enabling project-wide bat
:pedit
Vim has a built-in preview window — a special window distinct from regular splits.
:wincmd
:wincmd {key} executes any {key} window command from the Ex command line or from inside a Vimscript function.
