I realise this article is months old at this point, but some of these commands seem to be dependent on your own mappings?

i.e. In vanilla vim/neovim:

- `shift + w` - as shown in the cheat-sheet image you've appropriated - moves to the beginning of the next word.

- typing `ii` in insert mode will just insert two `i`s.

- `ctrl + r` - again, as shown in the cheat-sheet image - redoes an undone change (e.g. after pressing `u`/`U`)
