Vim comes with an exhaustive and fully indexed documentation that contains the answers to most of the questions you may have on using Vim.But the documentation is huge and may look to the neophyte as an impenetrable maze. Here are a few guidelines to help you find what you needThe :help command is your gateway to Vim's documentation. Read the first screen now.:helpLet's go meta::help helpYou can complete the arguments with <Tab> and display the list of possible completions with <C-d>.:help buf<Tab>:help :w<C-d>By the way, here is an explanation of key notation::help key-notationMost Ex commands can be shortened to a few characters. That's true for :help too::hThe :help command and its tab-completion are case-insensitive so the two commands below will get you to the same section::h BufWritePost:h bufwritepostNote that a and A are both legitimate commands so case-insensitivity doesn't apply.If you only have a generic keyword to search for, use :helpgrep and open the quickfix window::helpgrep quickfix:copenUse <C-]> on the highlighted words to jump to the corresponding tag, use <C-t> to come back.See :help tags for more.Scroll around to see if there's a related option or command that better suits your needs. That's a great way to learn new tricks, too.Use the right syntax to search more efficiently::h :command                         help for ex-command 'command':h 'option'                         help for option 'option':h function()                       help for function 'function':h modifier-key                     help for 'modifier'-'key' in normal mode:h mode_modifier-key                help for 'modifier'-'key' in 'mode':h mode_modifier-key_modifier-key   help for 'modifier'-'key' 'modifier'-'key' in 'mode'Examples::h :sort:h 'ai                 only one quote needed:h bufnr(              no need for both parenthesis:h v_ctrl-g:h i_ctrl-x_ctrl-o:h ctrl-w              no mode required for normal modeAnatomy of a :help section::help ballooneval'The words highlighted in red are the tags associated with that option.The words in green are the long form and the short form of the option name.The first line in white says that it's a boolean option and that it's off by default, see :help options.The second line in white says that the option is global, see :help option-summary.The purple lines are self-explanatory.Then comes the description of the option.The turquoise words are tags that let you jump to another part of the documentation. Don't be afraid to follow them.Use your brain, find logical patterns that will help you for future searches.Once you have found the handy :help list-functions, where to look for string-related functions?Once you have found :help i_ctrl-x_ctrl-o, how can you find help for <C-x><C-l> in insert mode?RTFM is not an insult. You will learn a lot more by reading the documentation than by asking short-sighted questions to random strangers so make sure you at least tried to Read The Fantastic Manual before asking.
