Re: erasing a macro.

Press "P" and hold down until it flashes twice. Type in the macro learning code (995). Punch the button where the macro to be erased is stored (or if a stacked macro, press P, then the macro button). Then press and hold down "P" until remote double flashes. This comes from the Radio Shack online manual mentioned in the first post above.

I have tested the above procedure and it works.
