sorry for being dense, but I can't seem to save files or do anything seemingly practical. Is there any practical use cases for this library, or is this purely along the lines of "Hey checkout this cool hack!"

It is a text editor, not a file server.

It is similar to CodeMirror, Ace, and Monaco.

When I was working on the Sage Notebook, circa 2007, I made the best textarea-IDE I could... folks requested vim and emacs bindings but browsers just weren't ready. Heck, I wrote my own javascript console because iirc only Firefox had one at the time, I digress... I look forward to a vim plugin for the IPython notebook!

I used this back in the day and it worked pretty well. Not sure how it cooperates with the newer Jupyter makeover but worth a shot!

For the moment I'm going with hack.

I hope the author will work out some of these kinks so that it becomes usable !

I haven't tried it yet, but that should still make it as useful as pasting text into vim to make changes quickly. Things like highlighting a sentence and making it all lowercase or uppercase is very simple. (v/V/C-v for one of the visual mode selection types, then pressing u after the select makes it all lowercase, and ~ can swap case if you had capslock on and typed "sOMETHING LIKE THIS"). There's also :sort for quick alphabetizing and the classic :s/word1/word2 text replacement.

The register "* is visible but doesn't seem to reflect the clipboard or similar. I agree that it would be great if it were supported.
