I am setting up a MagicMirror and so far I’m just mad that I haven’t done it sooner.

I’d like to get some advice on how to accomplish what I want to do. Mostly, I want the screen to show a slideshow of images but if someone presses a key on an attached keyboard, it would switch to the MagicMirror. I plan to use one of the cheap 3-button macro keyboards for this.

Is this even possible? I’m wondering if a screen saver would work but I suspect that MM disables screen savers (if they’re even available for the RPi).

I would love to hear any suggestions, even just pointers to what I should be looking for.

Thanks!
