Yes, and thanks for this. In addition, install

# pkg install xbindkeys

and add/create in ~/.xbindkeysrc

"intel_backlight decr"
        Alt + F6
"intel_backlight incr"
        Alt + F7

Than you can just use Alt_l +F6/F7 for this, for example, as they are labeled
with the symbols of up/down brightness in the Acer C720.

La referencia de la Duma a la anexión de la RDA, en este caso al contrario con la Crimlía sin
referéndum, no solamente tiene gracia sino da en el blanco.-
