Very inconvenient especially when every other browser known to man allows this. This is a major drawback for Brave, and it is not intuitive to use ALT + left arrow, when 1 key can do the same thing.
I read in another thread on here that in a “future” release of Brave, it will allow users to make their own shortcuts. I suggested this in a different forum for Brave a week ago saying Opera allows custom hotkeys users can replace. One of the reasons I like using Opera, that and the Battery Saver feature on that browser.
