D. Edit Button Layouts using Page View and NEW Keyboard Shortcuts
Moving buttons requires care, because MX-980 artwork is always either Left facing, Right facing or Wide (linking
two buttons together). The best way to move buttons around is in Page View (selected from the View
Menu). Double click on each page you want to re-arrange, then drag the pages so that you can view all of
them. Now, utilize the keyboard shortcuts to re-arrange buttons by SWAPPING them:
1 Both buttons are on the same page and the same side. Simply drag either button to the position of
the other button. If they are on different pages but the same side, hold down the ALT key and drag
either button ot the position of the other button.
2 Both buttons are on the same page but on opposite sides. Hold down the SHIFT key and drag either
button to the position of the other button. If they are on different pages and on opposite sides, hold
down both the ALT and the SHIFT keys and drag either button to the position of the other button.
