In Firefox I can assign each bookmark a keyword. When I enter that keyword into the address bar and press ENTER Firefox opens the corresponding bookmark. I use these keywords to quickly hop to different pages like Gmail (gm), Google Calendar (gc), and GitHub repos (fd, ld, and hk all open specific repos I use a lot).
As far as I can tell, this feature doesn’t exist in Brave (or any chromium-based browser). It’d be super nice to have – although I completely understand that this is a niche request.
