コマンド アクション Notes
vim file +54 open file and go to line 54 any : command can be run using + on command line
vim -O file1 file2 open file1 and file2 side by side
Insert enter insert mode so you can start typing. Alternatively one can use i ora.
Esc leave insert mode so you can issue commands. Note in VIM the cursor keys & {Home, End, Page{up,down}} and Delete and Backspace work as expected in any mode, so you don’t need to go back to command mode nearly as much as the origonal vi. Note even Ctrl+{left,right} jumps words like most other editors. Note also Ctrl+[ and Ctrl+c are equivalent to Esc and may be easier to type. Also Ctrl+o in insert mode will switch to normal mode for one command only and automatically switch back.
:command runs named command
:help word shows help on word Typing Ctrl+d after word shows all entries containing word
:echo &word shows value of word
:e set buffer for current window you can optionally specify a new file or existing buffer number (#3 for e.g.). Note if you specify a directory a file browser is started. E.g. :e . will start the browser in the current directory (which can be changed with the :cd command).
:sp new window above ditto
:vs new window to left ditto
:q close current window
:qa close all windows add trailing ! to force
Ctrl+w {left,right,up,down} move to window
Ctrl+w Ctrl+w toggle window focus
Ctrl+w = autosize windows to new terminal size for e.g.
:ba new window for all buffers “:vert ba” tiles windows vertically
:ls list buffers
gf open file under cursor
:bd delete buffer and any associated windows
:w save file Note :up[date] only writes file if changes made, but it’s more awkward to type
:sav filename save file as filename Note :w filename doesn’t switch to new file. Subsequent edits/saves happen to existing file

* searches forward for word under cursor # reverses direction
:%s/1/2/gc search for regexp 1 and replace with 2 in file c = confirm change
:s/1/2/g search for regexp 1 and replace with 2 in (visual) selection
K lookup word under cursor in man pages 2K means lookup in section 2
:make run make in current directory
Ctrl+] jump to tag Ctrl+t to jump back levels. I map these to Alt+⇦⇨ in my .vimrc
vim -t name Start editing where name is defined
Ctrl+{n,p} scroll forward,back through autocompletions for word before cursor uses words in current file (and included files) by default. You can change to a dictionary for e.g: set complete=k/usr/share/dicts/words Note only works in insert mode
