Either way now it shows as having the Backspace key assigned to it. I don't know why chrome and other browsers stopped using the backspace key to go back, but now it's ALT+Left arrow. 

About half my time is spent remote into my computer at work so it doesn't detect program switching, so having one back button for file explorer and web browsing was really nice

if anyone has any thoughts or could at lease verify for me that something has changed, I would appreciate it
