No need to have key labels if you already know the keys 😅.
But as explained in other comments, it’s all layers and chords. The space bar is actually 3 buttons. Left and right function as a space key if tapped, or layer 2 if held, so holding left or right space and q gives a 1. To get ! It’s the same key but with shift of course.
The center space key is just layer 3. So holding that and “I” is up arrow, jkl are left down right. Y is page up, h is page down.
Honestly, the hardest part is the missing : and ’ key. Those are so deeply ingrained.
