How to use "arrow-up" button to scroll in searched words history immediately after using isearch-forward

Question

Is there any way to use "arrow-up" button to scroll in latest searched words immediately after using isearch-forward? For now, in order to use the "arrow-up" key for this purpose, I am first required to do either of the following things:

1. M-p (mapped to isearch-ring-retreat in this context). Unfortunately my brain has limited capacity for remembering keyboard shortcuts, so I don't like this solution, "arrow-up" is more intuitive for me and I tend to remember it. Maybe I can bind the "arrow-up" key to isearch-ring-retreat only inside isearch context?
2. By clicking the mouse on the isearch prompt that had opened. This is inconvenient as it requires to use the mouse. Maybe I can change some isearch properties so that this happens by default?

Thanks!

Answer 1

OK, after further investigation I actually found a solution that seems to achieve what I was looking for. I added the following to my init.el:

(progn
  (define-key isearch-mode-map (kbd "<up>") 'isearch-ring-retreat )
  (define-key isearch-mode-map (kbd "<down>") 'isearch-ring-advance )
)
