Basics 4

- Open a line
  To insert empty line below cursor and toggle insert mode type `o`
  To insert empty line above cursor and toggle insert mode type `O`(capital o)
- Append command
  Normally when we insert text, its inserted before the cursor so in the word say `li`. If cursor at `i`. and we press i then type q then we have `lqi` so using 
  `a` first cursor is moved one character right and then goes to insert mode so if after using `a` we type q, then we have `liq`.
- Replace Mode
 Toggled by `R`(capital R). if it is on word say `the` and cursor is at beginning ie `T` then when we type Say then it will become `Say` not SayThe.
 NOTE: Replace mode is like Insert mode, but every typed character
      replaces an existing character
- Copy and paste
  Highlight the text to be copied. We can do this by going to visual mode by pressing `v` and moving cursor to select text. Press Esc to escape visual mode. Press `y` to copy and `p` tp paste. 
  y here stands for yank
  p stands for put
  
- Set option
  To alter some settings in nvim
  when searching to ignore case type `:set ic` 
  To turn off ignore case type `:set noic`
  To toggle ignorecase setting `:set invic`
  NOTE: If you want to ignore case for just one search command, use `\c`
      in the phrase: `/ignore\c` 
- Switch between windows
  `<C-w><C-w>` means Ctrl+w 2 times
  
- Creating startup script
Neovim is a very configurable editor. You can customise it any way you like.
To start using more features create an "init.vim" file.
  1. Start editing the "init.vim" file.

     `:call mkdir(stdpath('config'),'p')`
    `:exe 'edit' stdpath('config').'/init.vim'`
  2. Write the file with:
`:w`

- Auto Completion
  When typing any command to get the listed list of commands begining with whatever typed , press `<C-d>`. Now press `tab` to auto-complete it. 
  Eg: If we type `:e` then pressing Ctrl+d witll list commands starting from `e` and pressing tab will autocomplete with first result
- Switching between files
  When u have opened nvim in folder and that folder contains some files then use the relative path to access them by
  `:e main.c` or `:e Makefile`
