Using Logitec MX Keyboard without Logitech's [Options+][1] app. It works fine, but I can't control backlight on-duration.

There are key-mapping utilities, but I can't find one for backlight control. There is no key for this setting and I don't know of a shortcut, either.

**Can I control backlight on-duration with an app other than Options+?** I don't want to install it.

PS: When/How did functions like these become so locked down?
