A real time macro records the same amount of seconds a menu on your original device takes to come up.
For example, if the menu on your TV takes 3 seconds to come up, the One for All Remote will retain this information.
A regular macro sends out multiple functions to the selected devices, but it does not record real time.
You can only program a real time macro on the NETTV key. You can program a regular macro on the other keys.
