A lot of people have mappings like jk or jj to escape insert mode. The problem with these mappings is that whenever you type a j, neovim wait about 100-500ms (depending on your timeoutlen) to see if you type a j or a k because these are mapped. Only after that time, the j will be inserted. Then you always get a delay when typing a j.
Define your keymaps, commands, and auto commands as simple Lua tables, building a legend at the same time (like VS Code's Command Palette). A legend for your keymaps, commands, and autocmds, integrates with which-key.nvim, lazy.nvim, and more.
The Refactoring library based off the Refactoring book
...It integrates with built-in Neovim selection modes and can work with third-party tools like Telescope to present refactoring options quickly, enabling rapid transformation of code patterns. Beyond pure refactor actions, the plugin includes debugging helpers that insert print statements or remove them, aiding developers in tracing program flow and inspecting variable states as part of iterative development.
