Hello,
I’ve test the arrow key scrolling its working fine, but what is causing this issue is the key bind to the tabs you have.
If the tabs are selected, whenever you try to use arrow key scrolling it will switch to a different tab which will drag you back to the tab’s section.
To unbind the arrow keys from the tabs, please add this custom Js at Themes Options jQuery( ".circleFlipTabs" ).find('.ui-tabs-nav li').off('keydown')
Let me know if you need anything else
Best regards
