It's pretty simple to change things after the initial setup, just get back into the computer and tell the remote what you want to learn.
I believe you can setup independent macros such as a light controller, but I haven't tried.
You also can setup delay times for the IR flasher to control how the equipment comes on, such as a Plasma TV that will take longer to actually switch on as compared to a receiver.
The 890 and 1000 remote series are the new models that use both IR and RF and I'm not that familiar with them.
