A medical therapy device may include a user interface (6100) such as a combined touchscreen/dial user interface, for input of operation parameters. The user interface may include a dial and a touchscreen to display a subset of a list of items. Each item may represent a parameter of the medical device. The displayed subset may include a pre-selected item that may provide a pre-selection indication for a particular item. Rotation of the dial may move the pre-selection indication so it may change between items on the displayed subset. In response to a swipe gesture on the touchscreen, the displayed subset may scroll through the list. Also, the swipe gesture may cause pushing of the pre-selection indication against a boundary of the display such as in the direction of the swipe gesture such that the item associated with the pre-selection indication remains part of the displayed subset.
