The keymove concept will allow you to move a key from its present position to another key. Let’s say you wanted to move the mute button to another key because it will be easier to find when you want to use it, so you would use the keymove procedure. In the case of advanced codes, it will allow you to “move” the advanced code command to a selected key.

Let’s select a code that we know will probably work. Use 000, which is the power code. You can always change this to something else later.

First, be sure the 0027 setup code is assigned, and controls your receiver, even if it only the power key.

Second, select a key that you want to put the power command on.

Third, do the following. I have changed the procedures in the referenced thread to apply here.

Press and hold "p" until it blinks, then release
press 9-9-4
press the device key (in this case, the Amp key)
press "p" once
press the 3 digit advanced/discrete code 0-0-0
press the device key again (in this case, the Amp key)
press the key you want to use, which will then have the advanced/discrete code you assigned permanently entered

There is no need to exit the procedure; once you have performed the last step and pressed the key you want to use, the procedure ends itself, and you have to repeat all steps to assign another command to another key.
