The scroll action has a number of configuration options:
Direction
When using multiple pointing devices, including a mouse and touch, you may wish to configure the touch screen so that both devices scroll in the standard direction for those device types.
Scrolling in the "standard direction" means:
- For a mouse, the standard scrolling direction is where you rotate the wheel towards you and the page scrolls down. This is the way that mouse scroll wheels have worked since they were invented in the mid-1990s.
- Touch-based surfaces on the other hand generally work on a "drag" paradigm. The standard scrolling direction is where you drag the page in the direction you want the page to move (not the direction you want to scroll), so dragging upwards makes the page move upwards, which lets you view content further down the page, so you scroll down. This is the way that touch-based surfaces have worked since they first became popular in the mid-2000s.
There is a setting in UPDD Commander wherever a scroll action is associated with a gesture that indicates the scroll direction as seen in this example:
Smooth or Line-by-Line scrolling
In most cases, the scroll method is set to smooth to offer scrolling similar to a trackpad.
However, in one case we found that in a specific application, when in a specific mode of operation, our smooth scrolling produced fast scrolling with minimal movement. To cater for this specific case, we introduced a different line-by-line scroll method within the Advanced Options, similar to that produced by a mouse wheel.
This has been set as default for the ProTools application:
Scroll Axis
For certain gestures the scroll action will allow the axis to be defined, specifically those that only performed in a single axis like a horizontal, vertical, or single direction swipe.
