keystrokes.nvim

Show keystrokes in nvim.

This package is a proof of concept.

Add this plugin:

Plug 'kdheepak/keystrokes.nvim'

Start vim with the -W flag.

Example:

./build/bin/nvim -W ~/.config/keystrokes.txt src/nvim/main.c

This plugin provides a function that reads ~/.config/keystrokes.txt and displays all new changes to the file in a floating window.

If you add the following autocmd, it'll call the :KeystrokesStart command at your vim's checktime interval.

autocmd CursorHold <buffer> KeystrokesStart

This will show all recent keystrokes in a neovim floating window.

You'll need to patch vim/neovim for this to work.

In vim, you'll have to add it to this line:
