Unable to reassign 'menu' key at the Windows keyboard

Hello all.

Maybe I'm doing something wrong. But I'm trying to re-assign 'menu' key on windows keyboard to Command key.
When I press it, in "Type shortcut" window - in see action but displays nothing and in the Trigger Predefined Action I did not find just Command key press (it has only up&down, so I need to put different keys to up and for down?)
Does anyone manage to do this?
