Preset is switched in sequence by Preset Up/Down Button.
An application which is associated with the current preset in Application Launcher is closed by Close Button, or launched by Launch Button.
Configure the Preset Button of every preset file in the preset list in the same way(same S-Hold Time, LHold Time and Critical Time).

To use Close Button or Launch Button, check Use Launch Button or Use Close Button at Application Launcher for each preset file.

There is another way to switch the presets. You can switch a preset and launch an application directly not in sequence with Preset Button in the preset list. The application which is associated with the preset is closed by Close Button in the Preset List. Configure the Preset Button of every preset file in the preset list in the same way(S-Hold Time, L-Hold Time and Critical Time).
