For FORM action buttons, you can give the user access to all ten buttons by

!= "Set2". Add a computed field to the form called ABar, and give it a value of
"Set1" (this sets the default). Add another action button (this is your scroll
button), leave it nameless, choose the right-arrow icon for it, and give it the
following formula:
NewABar := @If(ABar = "Set1"; "Set2"; "Set1");
@SetField("ABar"; NewABar);
@Command([RefreshHideFormulas]);

!= "Set1" for the first set and @Environment("ABar") != "Set2" for the second
set. Give the scroll button the following formula:
