How do I backspace 4 spaces at once in Netbeans?

Question

I know that you can use Shift + Tab, but isn't there a more convenient way of changing the Backspace? If you're at the beginning of the line and you Shift + Tab, you don't go back to the previous line.

Answer 1

go to Tools->Options->Editor->Formatting then remove the check sign from "Use all languages settings" and then remove another check sign from "Expand Tabs to spaces".
