Vim Cheatsheet - Modes, Editing & Search Commands
The real barrier in Vim is not configuration but two layers of muscle memory: motions that let you travel precisely without scrolling, and search-and-replace patterns confident enough to run in bulk. On a headless server, editing nginx, sshd or live code, hjkl with count prefixes, ciw to change a word and :. to reindent turn a ten-minute edit into a one-minute one. Commands here are grouped by intent, moving, editing, searching and replacing, visual block and saving, rather than as an alphabetical list to memorise. A simple rule decides what to drill: whenever a task is "change this repeated text", reach for visual block or :%s, and confirm the hit count with a plain / search before committing. The closing group handles the two moments every newcomer hits, quitting without saving and writing a system file without sudo. Registers and macros handle the repetitive cases, and :copen turns the whole buffer of search results into something you can edit at a glance.

Save without quitting — the most common fix
:w编辑到一半需要存盘时用 :w，不必先 :q。配 :q! 可以丢弃改动强制退出，:wq 则是存盘并退出。
Output

Global replace with confirmation
:%s/old/new/gc
// c = confirm% 表示全文，g 表示行内全部，c 表示每次确认。批量改动时用 c 比直接 g 安全，误改能当场撤销。
Output
replace with new/new (y/n/a/q)?
Delete a whole line without entering insert mode
dd
3dd
yy
pdd 删当前行，3dd 删三行；yy 复制当前行，p 粘贴。Vim 的命令模式让你不用移动光标也能操作整行。
Search within the file and jump to matches

:nohlsearch/ 向下搜、? 向上搜，n 跳下一个。:nohlsearch 清除高亮——搜索后满屏黄色会看不清代码。
Common Pitfalls
- In normal mode i, a, o, p and d are all commands and change the file immediately; press Esc whenever you are unsure.
- :q! discards all unsaved changes irrecoverably — know the difference between it and :wq.
- Typing :q while still in insert mode does nothing; press Esc first to return to normal mode.
- Most Vim commands are undoable with u, but unsaved changes are gone once you exit — use :w during long sessions.
- An IME can swallow keystrokes in Vim; switch to English input when editing files containing Chinese.
Tips
- Stuck in Vim? Press Esc to return to Normal mode, then type :q! to force quit without saving.
- Forgot sudo when editing a system file? Use :w !sudo tee % to save with elevated privileges without reopening.
- Before a large substitution, use /word to confirm matches, then :%s — add the c flag to confirm each replacement.
FAQ
How do I quickly switch between normal, insert, and command modes in Vim?
Vim opens in normal mode; press i/a/o to enter insert mode and type, Esc returns to normal mode for motion and editing, and typing a colon switches to command-line mode while / enters search. Just remember that normal mode is for operations and insert mode is for typing.
What should I do if I opened a file without sudo and cannot save my changes in Vim?
There is no need to quit and reopen. Type :w !sudo tee % to write the current file (the % stands for the current filename) with root privileges. If the buffer is read-only, reload it first with :e %. The cleanest fix is to open it with sudo vim from the start.
How do I replace all occurrences of foo with bar across the whole file in Vim?
Use :%s/foo/bar/g to replace globally; ^ and $ anchor the start and end of a line, and dropping the trailing g replaces only the first match per line. To confirm each substitution individually use :%s/foo/bar/gc and answer with y or n.
How do I undo an edit, and redo after undoing too far in Vim?
In normal mode press u to undo the last change and Ctrl+r to redo it. Vim keeps a multi-level undo history so you can press u repeatedly to step back. To discard all changes use :q! to force-quit without saving.
How do I insert or delete content at the same column across several lines in Vim?
In normal mode press Ctrl+v to enter block-visual mode, move vertically to select the same column on several lines, press I to start typing at the top, then press Esc so Vim replicates the text down the column; press d or x to delete the selected vertical range instead.
