Copying, Moving, and Swapping Button Functions
The Control Console also allows you to copy or move functions from one
button to another, or swap functions between buttons, the same way you just
copied a function from the Function List.
To move a button’s function to another button:
Hold down the <Shift> key while you drag the image of the first button to
the second button (you’ll see a circle-M symbol attached to the button
image while you’re dragging it).
To swap functions between two buttons:
Hold down the <Ctrl> key while you drag the button image (a circle-S
symbol appears with the button image).
Please read Chapter 3 for more detailed instructions.
