Is there a hot key combo to delete channels from program guide?

I just got a Comcast basic package. There are a lot of channels that are not available to me. I know there is a way to delete channels from the program guide: left key to the channel call number/name column, click "select" button, then select "remove from channel lineup" from the pop-up menu. That's at least 4 clicks for each channel!

I am wondering if there is a hidden hot key (or hot key combo) for doing this simple task? I mean the good folks Tivo must have some tricks hidden under their sleeves, right?
