Access bookmarks quicker

When I want to open one of my bookmarks it gets annoying trying to press it accurately. So how about using the letter “B” combined with a number to open the 1st or 2nd bookmark on the bookmark bar. And for folders, they open up and we can use the arrow keys to shuffle through. My suggestion is being made cause it will make some processes faster and the lazier people’s lives, who don’t want to use the mouse, easier.
