The document discusses using Vim and Python together effectively. It provides tips for customizing Vim through options, mappings, and plugins to enhance productivity. Popular plugins are recommended for linting, autocompletion, fuzzy finding, Git integration, and more. Using Neovim over Vim is suggested for its modern features like asynchronous operations and Python integration. Setting up dotfiles is presented as a way to manage Vim/Neovim configuration across systems.

21. if you can get two keys for the price of one
♞+[X] ⇨ Ctrl+[X]

Why just another plain Ctrl key?

22. xcape
“xcape allows you to use a modifier key as another key when pressed and released
on its own. Note that it is slightly slower than pressing the original key, because the
pressed event does not occur until the key is released. The default behaviour is to
generate the Escape key when Left Control is pressed and released on its own.
(If you don't understand why anybody would want this, I'm guessing that Vim is not
your favourite text editor ;)”

40. vim or neovim?
Neovim
● works on modern systems only
● async (lint, tests!)
● python-neovim
● :terminal
● XDG directories: ~/.config/nvim/init.vim instead of ~/.vimrc
● modern defaults

41. .dotfiles

~/.dotfiles/config/nvim/init.vim → ~/.config/nvim/init.vim
