- Filtering and redirection can capture output from Vim or external programs.
- It's easy to change between backslash and forward slash in a file path.
- If you create your own tags file, you can jump to the correct line and column.
- If you work with many files, it's easy to save them all with :wa or :xa.
- Simple substitutes or a Perl script can convert text using HTML entities like >.
- The command :g/^/exe ".w ".line(".").".txt" saves each line in the buffer to a separate file.
- :g// lists all lines containing the last search pattern, and :redir will capture the results.
- With set browsedir=buffer the File, Open dialog defaults to the current file's directory.
May 2010
- @: will repeat a colon (Ex) command (and @@ will repeat again).
- You can use :g/^\s*$/;//-1sort to sort each block of lines in a file.
- It's useful to map . .`[ to repeat the last command and put the cursor at start of change.
- You can open a web browser with the URL in the current line.
- With --remote-send you can close a Vim you left open remotely.
- If you're used to Perl regex, you can use Perl compatible regular expressions.
- In insert mode, Ctrl-Y inserts the character above. You can make it insert the word above.
- A user-defined command can evaluate :Calc sin(pi/2).
- It's sometimes better to not use the slash delimiter for :s/old/new/.
- You can drag & drop one or more files into gvim.
April 2010
- zz scrolls the current line to the middle of the screen; scrolloff can keep it there.
- Vim can do calculations using Python, Perl or bc.
- You can wrap long lines while moving the cursor by screen lines.
- A tricky search can find text that does not match.
- Pressing % jumps to a matching bracket, and matchit.vim can match much more.
- The shortmess and cmdheight options allow you to avoid "Hit Enter to continue" prompts.
- An option controls how backspace and other delete keys work in insert mode.
- You can display line numbers and change the width of the number column.
- It's easy to change text between lowercase and UPPERCASE.
- The command history allows you to repeat several commands, possibly after editing them.
March 2010
- Vim tutorials has videos illustrating simple and advanced topics.
- Use % to jump to the matching bracket, and more.
- Use :lcd %:p:h to change directory to the file in the current window.
- ga shows the ascii value of the current character.
- You can list changes to the current file, even old changes.
- Use za to toggle folds open/closed.
- The status line can show your fileencoding and bomb.
- In a program, you can jump to the beginning or end of a code block.
- With two related files in a vertical split, you can scroll both windows together.
- It's easy to count the words in a file or block.
- You can even make a frequency table counting the occurrences of each word!
February 2010
- Vim tutorials has videos illustrating simple and advanced topics.
- You can press * to search for the current word.
- Ctrl-A can increment numbers.
- After typing a couple of characters, you can complete a word with Ctrl-N or Ctrl-P.
- Vim's help use prefixes like v_ (visual mode) to show the context.
- The :let command can set registers and options as well as variables.
- The command :42 jumps to line 42, as does typing 42G.

January 2010
- Vim tutorials has videos illustrating simple and advanced topics.
- We have an explanation for how :g/^/m0 reverses all lines.
- In a search pattern, \_s matches a space or tab or newline character.
- A script can use a test like &buftype == "quickfix" to check if it is operating in the quickfix window.
- Typing =i{ reindents the "inner block" (code inside braces).
- Using 'smartindent' means that typing # may remove an indent before the #.
- The 'winaltkeys' option controls whether Vim handles Alt keys.
- If you would prefer Y to be consistent with C, use :nnoremap Y y$.
- A plugin should set its "loaded" variable to show its version, for example let g:loaded_dbext = 503.
- We have a short FAQ for new users concerning common issues raised at #vim.
- You can use :cnoremap to map a key to <C-\>e(...)<CR> which will replace the command line with the (...) expression.
