The pink dots are stickers, and if "indexing" means "I need these so I can keep track of which row I'm touching", then yep, that's what they're for. 😁 I can keep track of where my fingers are with only three rows, but with only two thumb keys I couldn't just remove the top row like I used to do on the Moonlander. I actually like this even better, and I'm going to put the stickers on the Moonlander, too. They're often called "gem stickers" or "jewel stickers" in shops.
