Based on discussions here that I seem to remember reading, you CAN do the following:

1) Program a macro to a button
2) Restore the original function of the button using advanced codes to overwrite the macro function for that device.
3) Repeat this for every other device you don't want the macro.

Now, if assigning an advanced code will work, how about using the clear function?:

DEVICE-MAGIC**-9-9-4-key1-key1**

What about a key mover operation? (It *should* work.)

Can someone try this and see if it works?
