Reset history

After a couple of conversational sequences I feel that I finally manage to provide a good input that would generate the response I’m looking for.
However, because the model is still aware of the previous conversation it still keeps into account some of the information.

At this moment I simply start a new chat and copy paste the previous input.

However, I would find it much easier to just press the up key to bring the previous input (asked for this as separate feature) and disable history. (or even better, press Cmd+Enter or Cmd+Shift+Enter to start a new chat with the given input)
