Edit The Current Command Prompt

A neat feature of bash is the ability to open whatever the current state of the command prompt is into your default editor.

Let's say we have a really long command that we've just tried to run, but it failed and we need to make a small change somewhere in the middle. Instead of holding the left arrow key for 30 seconds, we can instead hit CTRL-X CTRL-E.

This pops us into our EDITOR (or maybe VISUAL, not sure which). In my case, that is nvim. I now have access to all the features I'm used to in nvim for quickly navigating to and editing, searching and replacing, or whatever.

Once I've got the command how I like it, I can save and exit (:wq) and the updated command will be executed.

This is similar to the fc builtin, which also happens to be available for zsh.
