-- Keymaps are automatically loaded on the VeryLazy event
-- Default keymaps that are always set: https://github.com/LazyVim/LazyVim/blob/main/lua/lazyvim/config/keymaps.lua
-- Add any additional keymaps here

-- TODO: There are mappings that I did not port yet
-- For instance: https://github.com/mjacobus/lvim/tree/main/after/ftplugin
-- https://github.com/mjacobus/lvim/tree/main/after/plugin
-- https://github.com/mjacobus/lvim/tree/main/autoload
-- https://github.com/mjacobus/lvim/blob/main/after/plugin/legacy_setup.vim#L179-L212
-- Maybe some here: https://github.com/mjacobus/lvim/blob/main/lua/config/mappings.lua
-- And here
