  According to the manual, Fn+R adjusts the display refresh rate.
Map Fn+R to KEY_DISPLAYTOGGLE.

Thank you for your contribution, it has been applied to my local
review-ilpo branch. Note it will show up in the public
platform-drivers-x86/review-ilpo branch only once I've pushed my
local branch there, which might take a while.

Thanks.

Oh, I somehow missed that. I found it on a Yoga 7 14ARB7.

Newer Yogas and Legions with 60Hz/90Hz displays have this refresh rate
toggle feature.

I'm wondering if this would be worth a new KEY_REFRESH_RATE_TOGGLE
event code? 

KEY_DISPLAYTOGGLE is used to toggle the LCD on/off in other drivers.

What do you think?

Thanks,
Gergo

At least to me it felt like an abuse of KEY_DISPLAYTOGGLE because it's 
obviously different. But since there was existing, similar use for it 
already, I didn't push back on it but took your patch.
