Keyboard navigation with HUD enabled?

Does keyboard navigation work when the HUD is enabled? I know the HUD is enabled, because when I move the mouse it appears and I can control my slideshow with it. My understanding was if the HUD is enabled and I check the appropriate choices in the iScreensaver options for Enter/Return, space bar, and arrow keys that those keys will trigger the HUD and allow navigation as well, but they don’t seem to be working on my Mac running Catalina.

Hi Tom - sorry about the slow reply, we didn’t notice this post.
Keyboard control works with the HUD enabled in all OSs except for Catalina. This is due to an Apple change in how screensavers work in Catalina. It affects other mac screensavers as well. We’ve asked Apple about it, but we aren’t confident that it will change any time soon.
If you really want keyboard control on Catalina, then you can do this trick: instead of installing the screensaver, just run the screensaver installer app and hit the Preview button. In this mode, running as an app, keyboard control is fully functional even in Catalina.
