This is a very obvious and rather critical feature and exists in basically every other browser: search for / find matches to a particular word or string within the text on a page, highlight them, and scroll them into view instance by instance.
Here it is implemented in Brave:
It saves a LOT of time and enables keyword checking to avoid reading an entire page or site or document and potentially missing something.
It allows quickly checking if a page contains needed information, finding one's prior location in a very long page by searching for remembered context, and e.g. looking for prices and dollar values by searching for currency symbols, for hours of operation by searching for :00 or :30, and more.
Usually it's integrated into the swings menu to m but it really deserves its own icon in the control / nav bar.
