I tried it out for a few mins. Can you unlock shortcuts like CTRL+W or CTRL+Arrow Keys, later on? I made some mistakes typing.
Oh, it was nice. I think I'm gonna show it to my friends who wants to learn bash. It's almost like using the real terminal.
Adding other shortcuts for navigating text, deleting text, cutting/pasting, etc. would be nice. On the reddit post you mentioned that you made this for your kid to learn bash, right? I guess it would also be nice to implement a tutorial for shortcuts too.
