Exercises 3: Editors (Vim)

Complete vimtutor. Note: it looks best in a 80x24 (80 columns by 24 lines) terminal window.
Download our basic vimrc and save it to ~/.vimrc. Read through the well-commented file (using Vim!), and observe how Vim looks and behaves slightly differently with the new config.
Install and configure a plugin: ctrlp.vim.
1. Create the plugins directory with mkdir -p ~/.vim/pack/vendor/start
2. Download the plugin: cd ~/.vim/pack/vendor/start; git clone https://github.com/ctrlpvim/ctrlp.vim
3. Read the documentation for the plugin. Try using CtrlP to locate a file by navigating to a project directory, opening Vim, and using the Vim command-line to start :CtrlP.
4. Customize CtrlP by adding configuration to your ~/.vimrc to open CtrlP by pressing Ctrl-P.
To practice using Vim, re-do the Demo from lecture on your own machine.

Configure your other tools to use Vim bindings (see instructions above).
Further customize your ~/.vimrc and install more plugins.
