Ask HN: What do you think about adding Unix Command like feature to ChatGPT?

When using ChatGPT, I've frequently found myself hitting the "up arrow" key to retrieve my previous prompts, so I can modify them, like you would on a Unix command line.

As Sama visits this site, just thought I'd ask: Is this something that could be added?

Or are there shortcuts I just don't know about? I asked ChatGPT itself and it told me it was not possible.

What do HN'ers think?
