If you hold down the Alt/Option key, the selected layer(s) will be duplicated directly into a new document.

Select this checkbox to duplicate the selected layer(s) before moving them with buttons #4 to #7.
The selected layer(s) are moved step by step to the top of the layer panel. This function can be found under Layer -> Arrange -> Bring Forward
The selected layer(s) are moved step by step down in the layer panel. This function can be found under Layer -> Arrange -> Send Backward
The selected layer(s) are moved to the very top of the layer panel. This function can be found under Layer -> Arrange -> Bring to Front
The selected layer(s) are moved to the bottom of the layer panel. If there is a background layer, it is unlocked and the selected layer(s) are moved below it. This function can be found under Layer -> Arrange -> Send to Back (but without unlocking the background layer).
If you hold down the Alt/Option key while performing steps #4 to #7, checkbox #3 will be reversed and therefore does not need to be changed for a one-time application.
The order of the selected layer(s) will be reversed. This function can be found under Layer -> Arrange -> Reverse
Right-clicking on a button shows you all available functions, so you don't have to remember the keyboard shortcuts.
