Can define macros to repeat tasks in vim
	qv # record macro on letter "v"
	{O\begin{verse}ESC # Go to start of paragraph and insert text
	}O\end{verse}ESC # Go to end of paragraph and insert text
	kkV{jj # Move up 2 lines, select mode (whole line), move to line 2 in paragraph (selected)
	:norm A \\ # On each line selected, run "insert \\"
	}jzzq # Move to start of next paragraph, center screen and end the macro
	@v # Repeat macro

Say you want to format footnotes "(1234)" into latex form
	qfdi( # Record macro - Cut out text in brackets
	^CTRL-r") # Go to start of line, go to line with that text (e.g. 1234)
	daW # Delete around word, leaving just the actual footnote content
	D'' # Cut to end of line and go back to previous position
	/() # Search for empty brackets (where footnote was extracted from)
	la\footnote{}ESChp # Move, insert "footnote {}" text, move, and paste footnote text inside {}
	F)da( # Find ")" and delete around () to delete ()
	/([0-9]\+)q # Search for next footnote like (1234) or (1) - and end macro
	10@f # Repeat macro 10 times - once it stop matches it ends

	# Could also run @f inside the macro to make it recursively run to the end

Another thing you can do is "." repeats your last command
	:g/^@/m$ # Globally (for all lines) move lines starting with @ to the end

	:earlier 10m # Go back to changes from 10 minutes ago
	:later 10m # Go forward (undo "earlier") - can even do hours

Use "plugged" to manage vim plugins in .vimrc
	call plug#begin('~/.vim/plugged')
	Plug '...' # Line for each plugin name
	call plug#end()

	:PlugInstall
	:PlugUpdate

	# goyo plugin centers text in vim - more readable
	# vimagit plugin manages git using vim (commit changes by writing config lines)
	# vimwiki plugin lets you view vim wiki

	set number relativenumber # Shows line number relative to current position
	set wildmode=longest,list,full # Autocomplete on vim command line
	autocmd FileType * setlocal formatoptions-=c ...-=r ...-=o # Turn off auto commenting

	set splitbelow splitright # Split vim to the right/below by default

	# Use "map" to set your own keybinds
	map <leader>o :setLocal spell spelllang=en_us<CR> # Turn on spell checker
	map <leader>s :!clear && shellcheck %<CR> # Check a script for issues/posix compliance

	# Sometimes need to force vim to load certain files as certain formats
	let g:vimwiki_ext2sysntax = {'.markdown': 'markdown'}
	autocmd BuffRead,BuffNewFile *.tex set filetype=tex

	# Copy selected text to system keyboard (requires "gvim")
	vnoremap <C-c> "*Y :let @+=@*<CR>
	map <C-p> "+P

	autocmd BuffWritePre * %s/\s\+$//e # Remove trailing whitespace from files

Can turn vim into an IDE for html by using keybinds and macros
	# .vimrc
	set nocompatible
	filetype plugin on
	syntax on 

	# Map "space-space" to find <++>, delete it (to empty buffer) and go to insert mode
	inoremap <Space><Space> <Esc>/<++><Enter>"_c4l
	# Map ";i" to wrapping text in <em> (emphatic) tags - but only for html files
	autocmd FileType html inoremap ;i <em>/</em><Space><++><Esc>FeT>i #

Use .vimrc to manage everything - can set colour XResources (to be universal)
	set hlsearch # When searching, highlight all results
	set incsearch # When searching, highlight as you type
	set clipboard=unnamedplus # Now clipboard is shared between vim and system

	set tabstop=4; set softtabstop=4; set shiftwidth=4 # Set tabs to 4 spaces
	set expandtab; set autoindent; set fileformat=unix # Force use spaces over tabs

	set nocompatible # Required for vim to work normally on windows
	syntax on # Turn on syntax highlighting
	set encoding=utf-8 # Set text encoding to normal
	
	set wildmode=longest,list,full # Turn on autocomplete with ctrl-n

	# CTRL-w v and CTRL-w h split the vim window - move with CTRL-w arrow keys

	nnoremap S :%s//g<Left><Left> # "S" does global search
	nnoremap <silent> <C-t> :tabnew<CR> # "CTRL-t" open a new vim tab
	map <S-Insert> <C-i> # Map shift-insert (paste system clipboard) to CTRL-i
