Speed presets define the text scrolling speed in words per minute ("WPM" parameter).
Keyboard key is assigned to each speed preset: 1 – 10 for scrolling in normal/backward direction. The default keys can be changed according to your preferences.
The USB game controller supporting analog input, i.e. input device, is also configured here. To define the movement axis for the input device, choose the required option from the drop-down list.
Once the USB game controller is connected and detected by the system, the speed indicator line turns white. To define the text scrolling speed, move the device controller stick in opposite directions along the chosen axis. These movements are correspondingly displayed on the speed indicator line:
The device controller stick is moved to the left
The device controller stick is moved to the right
To swap the speed acceleration and slowdown, select the "Invert" checkbox.
