Backspace key in Safari no longer goes back a page
In Snow Leopard pressing the Backsapce key (the one that moves the cursor from the right to the left to erase a character) when I was in Safari would take me back to the last visited page. This no longer works in Safari and there is no way I can find to switch this very useful behaviour back on.
Is it me or is this no longer possible?
TIA
