According to this link (KendoUI for Angular) it says "Once the component is focused, the user can navigate with the Left Arrow and Right Arrow keys".
And you can see that it works as stated above in this example KendoUI for Angular ScrollView.
However, KendoUI for jQuery ScrollView does not seem to have this left and right key navigation option. Is it actually not supported in KendoUI for jQuery ScrollView? How can I add the support for the left and right arrow keys in this scenario?
