Keypad

The following section describes how to interact with the ColecoVision controller's keypad buttons. webЯcade provides two different ways to interact with it (the Radial Keypad is not available in Super Action Controls mode):

Radial Keypad (quick-select)

Radial Keypad

Moving the right analog stick in a direction brings up a 12-key radial (pie-menu) selector, arranged clockwise from 12 o'clock: 1, 2, 3 (top), 4, 5, 6 (right), 7, 8, 9 (bottom), *, 0, # (left). Point the stick toward a key and confirm with either the Left or Right Bumper to press it. Releasing the stick back to center dismisses the selector without pressing anything.
