@AndrewK Hmm, well whatever our interpretation of the manual is, it is strange that there is different behaviors on the two machines.
<br>
I'd be happy to help you setup the windows computer to how you expect it to behave.
If I understand correctly, you want the right arrow key to go through each slide in a item, and once it reaches the last slide, it should switch to the next service item.
<br>
To get this behavior, you can switch the shortcuts for the vertical and horizontal arrow keys, and make sure OpenLP overflows to the next service item:
Open the configure shortcuts interface (manual - customize shortcuts)
Scroll down to the "Live Toolbar" category
Set "Previous Slide" and "Next Slide" shortcuts to some temporary, arbitrary keys such as "J" and "K"
Set "Previous Service" and "Next Service" to the now unassigned "Up" and "Down" keys
Go back and set "Previous Slide" and "Next Slide" to the new unassigned "Left" and "Right" keys
Close the shortcuts panel and open the "Configure OpenLP" panel.
Open the "Advanced" tab in the settings
Under "Service Item Slide Limits", select "Move to next/previous service item".
Close the settings
I hope that helps!<br>

P.S. The manual is a little unclear; In the Moving Through a Service section where it states:
you can use the Right Arrow key on your keyboard to
move down through your service
It means down through the service list, not through individual slides. The section following that, titled Moving through a song bible verses or images contains the information about switching through slides within service items.
