Yeah, the website is very early and I just implemented basic commands. I plan to implement keyboard shortcuts, history, and all other fun shell stuff.

I’d say keep that one. It’s a fun little bit of meta

There isn't one to keep, its just keyboard shortcut in chrome(??)

He means, don't override it to give it its normal shell meaning, as the current meaning (add bookmark) is pretty desirable for him as owner of the site.
