+**EDIT 2024-04-16**: turns out that there's a [built-in](https://www.computerhope.com/unix/uhistory.htm), `fc`, which does basically the same thing, though it edits the command that was _just entered_ (which is typically what you want when you encounter an error or want to do "the next thing", anyway).

 While reading through my dotfiles, I found some [configuration](https://github.com/scubbo/dotfiles/blob/690f907f9ae36e36fed9851eac3a4ff2c20d7905/zshrc-local-mactop#L144-L147)[^1] that didn't seem to be working - it claimed that `<ESC>,v` would allow editing of the current line in vim, but that didn't seem to work. I guess I'd copied that from some other configuration and lost patience with trying to get it working, or that it relied on some other configuration option which had been broken[^2]. I dug in to find out more. ([This article](https://thevaluable.dev/zsh-line-editor-configuration-mouseless/) was invaluable!)

 [^1]: Still in Github until I fully migrate to my self-hosted [Gitea](https://gitea.scubbo.org/) instance. I'm cautious of a circular dependency here - Gitea would need to be up-and-available to source dotfiles, but dotfiles would be referenced as part of the setup process for hosts (including the one that runs the Gitea instance).
 [^2]: An idea - regression testing for dotfiles? Don't tempt me...
 [^3]: The [article](https://thevaluable.dev/zsh-line-editor-configuration-mouseless/) says that the ZLE _is_ the command prompt, which...seems unlikely to me? I would think that the ZLE is a part _of_ the command prompt, but not all of it? Although the article contains a lot of useful information and insight, it also has some rather loose and imprecise statements, so I'm not sure how much to trust this.
-[^4]: `bindkey -v` is an alias for `bindkey -A viins main` - in ZLE, you don't set a keymap as active, instead you set a keymap as an alias for `main`, and I think that's beautiful.
