Ok, how much did you hate having to do the zz? It is annoying. Instead, lets tell vim to do it for us.

:set scrolloff=8

Now lets scroll around. How does it feel. SO GOOD.

Lets quit out of our previous vim experience and curl down this file.

curl https://raw.githubusercontent.com/ThePrimeagen/vim-fundamentals/master/course-website/lessons/some-javascript.md > exercise.js && vim exercise.js

After following the delete instructions you should notice that its really hard to count how many lines of code huh? Type the following

:set number

You will notice a new column has been added and now you have line numbers! Yeah its pretty easy to a jump, but also not all that easy. Math can be hard sometimes.

" sets relative numbers
:set relativenumber

" turns off relative numbers
:set norelativenumber

Wow. Much better huh? You can jump easily now. You may not be good at jumping yet, but you can see its a lot easier. Lets play around.

Put your cursor on foo and press v10j. What happened? Press V to highlight the whole line.

Ok lets leave vim, :q and reopen back up the file either by reexecuting the curl command or simply executing vim exercise.js

What happened?

Commands you execute only live for the session you have vim open. This is painful right? Well, actually not. There is a .vimrc! All is not horrible. So lets create one!

Create a vimrc in the correct location with the following content.

set scrolloff=8
set number
set relativenumber

Open up vim again. Ohh yeah! This is great, but those tabs have to go (tabs vs spaces anyone?)! Add these lines to your vimrc and restart vim.

set tabstop=4 softtabstop=4
set shiftwidth=4
set expandtab
set smartindent

Now restart vim... what just happened? Pretty cool huh?

How do you know what is available?

• You can google. Sometimes that is a good thing.
• h options
• h <tabcomplete or ctrl-d>
• h <specific option name>
