How to change default actions in KDE Global Keyboard Shortcuts?

Question

KDE

There is a Lenovo B590 laptop with an Intel graphics card. OS OpenSUSE 13.1. It seems to me that KDE Daemon changes the brightness of the display by pressing hotkeys through the files located in the directory /sys/class/backlight/acpi_video0 and this does not work correctly (the minimum brightness is at 20%, when the brightness drops below this value, the display brightness increases) . I want to make a change in brightness through the files of the /sys/class/backlight/intel_backlight directory, through which everything works correctly.
