I would like to select last, and then add the selection before the last selection onto it. It would also be really nice if the last toggled through the last 4 selections.
For Example:
1 + 2 [Enter]
3 + 4 [Enter]
5 + 6 [Enter]
[Select Last] - Selects Channels 5 + 6
[Select Last] + [Select Last] - Selects Channels 5 + 6 + 3 + 4
[Select Last] + [Select Last] [Select Last] - Selects Channels 5 + 6 + 1 + 2
