Duckduckgo search bar is infuriating here. I'm always pressing Home/End to edit my query, and those keystrokes don't register.
I just checked and it seems like they hijacked it so it navigates the search suggestions instead (ie. pressing "end" goes to the last suggestion)?
It also means if I've pressed page down, then press down it jumps upwards to the top of the page.
Extremely user-hostile choices.
