Loop 1 Full Pattern

I would like to temporary loop a whole pattern by pressing the numpad enter. I know the largest selection is 1/2. I know there has to be another keyboard shortcut to accomplish this. What is it?

2nd button in the Transport controls is Pattern Loop:

Mapped to [CTRL] + [Scroll Lock] by default.

Perfecto. Thanks!
