Improvement to arrow-navigation in address bar

Hi,
I’m currently doing a lot of web research using Brave as my main browser and one feature that I miss multiple times daily that should be very easy to implement is the following:
when the cursor blinks in the URL bar, pushing arrow-up should make it jump to the very front of the URL or the input text while pushing arrow-down should make it jump to the very end.
You might object that the vertical arrows are already reserved to navigate suggestions that pop up beneath the URL bar when typing - BUT: you could just make it an extra step in between. Meaning on arrow-down, the cursor would first jump to the end of the URL/text and upon pushing it once more, the first suggestion would be selected. Likewise, arrow-up form the position of first suggestion (search) would then make the cursor jump to the front of the text.

Easy but really makes a big difference!

Thanks.
