Can NetBeans remove trailing whitespace and change tabs to spaces on save?

Question

I just started to use NetBeans, and am trying to work out how to:

1. Make it so that trailing whitespace is removed on save. I know that you can invoke it manually

Answer 1

Tools > Options > Editor > On Save > Remove Trailing Whitespace From: None / All Lines / Modified Lines Only

This is as of Netbeans 7.3, according to Webmut.
