I'm trying to learn emacs too - last night I kept ChatGPT open and asked it any questions I had ("what's the hotkey to open up a new window below the current one") and I'm getting better really quickly.
Yes, I just said I'm using Pulsar. I don't think it has a future though, since the community seems to be gone (so all the extensions are unmaintained). Hopefully I'm wrong. For now I'll just keep using it until I run into something too broken to work around.
