How to copy a block of text up in IntelliJ IDEA?

Question

Java

I'm trying to work in Idea. Eclipse has two combinations Ctrl+Alt+Up and Ctrl+Alt+Down that copy the selected block or current line up/down. In Idea, Ctrl+D (Duplicate Line or Block) does the same, but the block is only copied downwards.
Question from the title: how in Idea to copy a block / line up in one combination?

Answer 1

Please clarify what is the difference?
For example, text:

function {
a,
b,
c
}

If I copy "b," down (Ctrl+D), I get

function {
a,
b,
b,
c
}

If you copy "up", you get

function {
a,
b,
b,
c
}

What is the difference?
