While I am fairly new to this hobby, I feel like I still grasp many of the concepts pretty well.
However, I'm a little confused on whether or not a keycap set of any % could be used for a keyboard that is a lower %. For example, could a 65% keycap set be used for a 60% keyboard?
I have this question because I was looking at the GMK Red Samurai's and saw that the 65% had this layout:

But it didn't seem like it could be used with a 60% layout like this:

Is this only happening here or does this apply to all keycap sets?
