Check out vimtutor if you wanna learn it fast

I oft reference the wikibooks page as well https://en.wikibooks.org/wiki/Vim






If your partner is a mac user and wants to feel like they’re using a mac, tbh I think the best option is to use Fedora Kinoite with a mac skin on it.
If they’re a power user and don’t care if things are under construction, they could consider Gershwin Desktop but I really wouldn’t recommend that for a daily driver unless you genuinely have unlimited free time.
