Luna Display has the ability to be used with a connected keyboard. Our team tested extensively with Apple’s Smart Keyboard specifically, but other keyboards should also be compatible.
Unfortunately, if you don’t have a keyboard, Luna Display does not have a built-in onscreen keyboard.
If you use another keyboard layout (such as Colemak or another, non-English language), MacOS will still remember your settings, but you may have to switch to your desired keyboard by pressing the language change (the globe on the Smart Keyboard) button until your desired keyboard is selected.
Something to note is that normal MacOS shortcuts will not work while using any iPad keyboard. For example, command+tab will not switch between MacOS applications, but instead the iOS applications will show up. This is due to any keyboard connected to an iPad being bound to iOS.
