Cant rename bookmarks

I cant figure out how to rename bookmarks using my bluetooth keyboard, assuming there is even a way to do that. Im using VoiceOver also BTW. Please make this possible. Also, I cant erase most visited sites, and have to erase things one by one in history, but would rather b able to erase everything from most visited, including the Amazon and Twitter links and so on, which I never visit, but are still listed. I cant seem to get rid of those in history. Sigh. Other than that, so far so good. Yay!
