i've used PC all my life but i'm switching to a Mac hopefully by the end of this year so i've been searching the internet looking at the minor differences (i.e. alt on windows is cmd on a mac) but there's one thing i was wondering about but i can't find it. in windows, when you're in the web browser and not typing anything, you can hit the backspace key and it functions as the back button. i used this keyboard shortcut a lot and i was just wondering if you can do this on a mac as well. thanks.
