Yep, they've got a cross on the underside.
Well here is the deal, I probably won't want to spend more than about $30 on new keycaps (I've just not got the cash right now).
The absolute deal killer though is that this has those two FN keys at the bottom and if you look at the keys around the right pinky finger they've all got multiple symbols on them.
I would really prefer that all keys are labeled with the various FN combinations for those FN keys. I don't want a guest user to have to ask me nor do I really want to memorize all the 3rd and 4th modifier patterns with this small keyboard.
This kind of rules out just getting a full replacement set, they won't have the Keychron modifiers listed on the keys.
The white keys kind of have to stay because they've got like 4 special symbols on some of them.
