Shortcut keys / Hotkeys don't work anymore in Chrome ?

Hi,

I usually used A&D (maybe Q&D, I'm using Azerty) keys to scroll through the images (jumped to the next one) on the page but it doesn't work anymore with the latest versions of AMR and Chrome (59 or 60 at least).

Any idea why?

S&W (S&Z) still work (but it's like up&down keys)...

Regards
